Likely the only difference you can ascertain are the details shifting a fraction of a pixel. My next question was, could I tell the difference if I increased or decreased exposure during post processing?

To test for that answer, I photographed the sliced fruit plate using a variety of exposures and the adjusted them as necessary in DPP. Natural subjects often have the finest details and, in this case, those details taste great.

I ate the fruit before I thought about the JPG capture being a good idea. In the first row, images were reduced by 2 stops during post processing and the second set were increased by 3 stops. Again, it is very difficult to see the difference in the too-bright captures.
