I dunno for you your right for me, not. I also drop a lot of files into a non linear editor and can usually see a big difference
bcooter,
to repeat, I am not denying that you see a difference; I am only disagreeing with you claim about what _causes_ that difference.
You seem to keep missing these points:
1) There is a systematic difference in design features such as the color filter arrays between the MF backs (plus the Leica M9) on one hand and the 35mm format cameras on the other. This is related for one thing to the different makers (Kodak and Dalsa for MF, Sony and Canon for the other) and the priorities of their different target markets.
2) This difference in color filtering and the way it effects subsequent processing needs is far more likely to be the cause of the differences that you see than differences in the electronic details of the photo-sites themselves.
Take this tip from a professional scientist: do not change two factors between two groups of experiments and then try to attribute the change in results to one of those changes while ignoring the other.
Geeky aside: Most CCDs are CMOS devices these ways; the difference is how those different CMOS chips then handle the electric charges after those charges have been gathered in the photo-sites:
CCDs move the charges around;
active pixel CMOS sensors use voltage-based signal transfers and charge amplification.
