They are the autosaved files from DSS, converted to 16bit, cropped, resized and saved for the web.
The only difference between them is that one has had darks taken (not ICNR) then subtracted, the other, no darks at all.
Take a look and then tell me if you see much of a difference.

What do you mean JJ, were your images taken as JPEG, JPEG darks subtracted and then converted to 16 bit?.

If so, then I wouldnt expect any difference between dark subtracted JPEGS (with JPEG darks) and no darks at all. Dark subtraction wont work with JPEGs (compression would mess with that).

Why would you convert a JPEG to 16 bit?. JPEGs are 8 bit, nothing to gain there.

I probably have missunderstood something here.
