Whilst not doubting the sincerity of the views expressed here, nor challenging the right of the individuals concerned to hold them, it is important to remember that the spread of the current pandemic is a consequence of the widespread, uncritical adoption by governments and trading blocks of unfettered, global, free-market economics.

The last time I checked, the Chinese were not responsible for the formulation and export of this 'one-size fits all' economic model, although they have become highly skilled at exploiting its more obvious flaws to their advantage with, it has to be said, the active, and in many instances craven, collusion of successive world governments, including our own.

I hope John Riley will allow me to answer this point from an economic rather than a political perspective whilst acknowledging that the two are deeply intertwined.

The Spanish flu of 1918 killed 50 million people worldwide. Free market economics as we know them today were but a dream in that time.

The current (but set to change drastically I feel and hope) free market economic model has brought millions out of poverty, given most in society a better standard of living and equally importantly improved the health of us all. Like most things that are "free", this means that the pendulum has swung too far in the free direction and I feel that in the decade to come we shall move a little back toward the "control" side of said pendulum especially with regard to public sector employees (NHS; care workers; emergency services etc), and that is essential in my mind.

The Chinese government have simple aims. To use the free market of the western world to grow their economy, enrich their population, and to increase their standing as a world power. They have achieved all this in the last 20 years without changing their political demographic at home. They are playing the west's game without having to answer to their people.

China has become incredibly wealthy as a result. Unlike N Korea or Russia for example who both have appallingly bad economies. I agree that the west has bent over backwards to assist China in these goals, and to a large part have benefited enormously from it. However they have also created a monster and there is no turning back.

Now, is there a way that the thumbnails in the folder are also done through FastPictureViewer so these look correct also?
No I dont think so. Because they are windows folders the display is governed by windows. You will also notice that FastPictureViewer cannot display TIFF files.

If by now any readers are wondering why use a wide gamut colour space when the advice seems to be to output everything in sRGB.....here is the answer.....

Anytime you edit a file (colour;exposure;curves;cloning etc), you risk bringing artefacts into the image. The more you edit the higher the risk. By editing a raw file in a 16 bit capable application and a wide colour space you limit those artefacts because the image has so much more information in it to begin with. When all your editing has been done, and probably saved as a 16 bit TIFF or PSD file in a wide colour space, you then can convert the profile to sRGB; resize the image; perform output sharpening; and then save as a (8 bit) jpeg.

Your 16 bit TIFF or PSD file can be retained too so if you ever want to do further work you can do so on that file.

Thanks Peter,
I'll get onto that freeware now and download it.
Here are the settings to enable colour management with FastPicture Viewer. If you have created a custom monitor profile then choose that from the drop down box.

Also, on LR export, should I keep it as sRGB as standard or export in PhoPhotoRGB?
Anything destined for the web should be sRGB jpeg.

If you export in ProPhoto two problems can arise. Jpeg is 8 bit format so you will not be getting exactly what you see when viewing the 16 bit image in LR develop module. Secondly anyone viewing on a non colour managed application will probably see whacky colours.

The only time you want to be exporting in ProPhoto is if creating a new DNG or PSD or TIFF file that you intend to do further work on in another application.

Flickr will display the jpeg correctly. The only problem you may have is if the image is then viewed on Flickr in a non colour managed browser. Most browsers are colour managed I believe. Firefox was the first to enable full colour management. Here is a good guide to set up Firefox correctly for full colour management......https://cameratico.com/guides/firefox-color-management/

One further thing to remember is that having worked on a raw file in LR in the native colour space (almost the same as ProPhoto, but not quite....google "Melissa"), when you export as a sRGB jpeg you are not getting an identical image colour-wise. The reason is that any colours in your working raw file that are outside the sRGB colour space will be converted on export into a colour that is in the sRGB gamut. Unless you are working with extreme "edge" colours, you probably will not notice a difference. But as an exercise compare the histograms and you will see they are not identical.

Viewing them using the built in picture viewer in Windows 10 but on the same screen / computer as Lightroom they were processed on.
Your problem is Windows built in picture viewer which is now just called "photos". It is not a colour managed application. It does nothing with the sRGB profile tagged to your image. If you use a wide gamut monitor the oversaturation will appear even worse. Use something like "FastPictureViewer" freeware and set up colour management within it to get the same image as you see in LR.

Haven't tried reimporting them back in but I presume as they were ProPhotoRGB in develop and exporting as sRGB and then going back into Lightroom as a ProPhotoRGB then they'd look back to normal?
No. Once you have exported an image as a sRGB jpeg that image retains the sRGB tag. On import back into LR it will be displayed as a sRGB jpeg. The colours will however be correct because LR is a colour-managed application.

Am I the only one who has a 90º add-on viewfinder from the film days to use when I really need to do low shooting?
No, I've got one, because I like the viewfinder more than the screen.
I use the viewfinder most of the time, but when critical focus is essential the Live View image zoomed 100% is more accurate. This is where the articulated screen is really useful.

However, the advantage of the K-70 screen over the KP, being fully articulated, is that low down shots are easy to do when the camera is used in portrait orientation, so I would give an extra mark to the K-70 design for that. Is it also possible to do that with the K-1's design?

In portrait orientation the screen can tilt 45 degrees up.
