To put this in perspective, if we scale up the 7.2 micron photosites
of the 1Dmk3 to the size 8.46 microns of the D3 photosites, the
scaled up photosites would have 54,600 electrons full well -- the
same within experimental error. It seems then that the D3 and the 1D
mark 3 have about the same level of sensor technology, just different
choices for sensor size and pixel pitch.

In other words, quantum efficiency is the same. I'm rather
disappointed that Nikon's elaborate microlens design hasn't improved
on the Mk III in this respect.

Hm, how big is the difference between 5D and Mk III in this respect?
Here is a comparison of QE to the 5D:
