So, all you folks with more experience, what am I missing?

D3s vs D700?

Even though I used liveview and tried to focus at the 125 on the shutter speed, it did not work out that way, and you are right, the A pictures are focused slightly in "front on" the B photos.

But, since this was mainly meant as a noise test, you can still see a little more blue noise on the A pictures compared to the B pictures; or perhaps I should say, that in the given light the D3 has a touch more noise in the blue channel than the D800 when down-sampled to 12MP.

BTW, the A/M switch decides whether the lens aperture is open or closed.
