dynamic range - dxomarks and dpreview do not give he same resuts

Beauty is in the eye of the beholder.  For example, many disparage shallow DOF photography, whereas I have quite a liking for it.  In addition, what is usual for one photographer may well be rare for another.

In other words, it's fair to say that you don't like the look of photos processed with agressive tone curves, just as it's fair for someone to say they don't like the look of shallow DOF.  Thus, wide DR may hold little appeal to you, just as wide aperture lenses might hold little appeal for another.  But that is not to say that others don't have an interest.

Precisely -- it's the "noise aesthetics" that determines the noise floor for "useable DR".  This is not to say, of course, that all will agree on the "appropriate" noise floor, but, in my opinion, it's a discussion worth having.
