That is the traditional thinking - that is being challenged here really, and it has been my suspicion for a while that we may be accepting a rendition of such scenes that is in fact constrained by the technology of single shots and the processing,

It may be more helpful to think in terms of 'constrained by the DR of the sensor' rather than 'constrained by the technology of single shots'. HDR is a method of extending the DR of the sensor - as is a grad filter.

Yes, I see, but I was including the limitations of the processing possibilities as well ... HDR frees us from many of these also.

Yes. But HDR, and PP shadow recovery, and highlight reconstruction and a grad filter are, in the present context, all just tools for compensating for the sensor's lack of DR. Each have their strengths and weakness - but the fundamental limitation is the sensor and if it's DR is sufficient none of the compensatory techniques are necessary.

The "darkest" DNG did encompass pretty much the whole dynamic range of the scene. The sensor's dynamic range is (close to) adequate, providing you expose to just avoid blowing highlights. If a conventionally "correct" exposure had been used, the highlights would have been blown - as in the "darker" DNG.

The processing that was applied to the "darkest" DNG was largely to correct midtones. Lightroom did have to raise shadows substantially to restore detail but the increase in resulting noise isn't at all obvious visually.
