5D3 vs 6D

Please, be specific.  What part of my reasoning "doesn't seem right"?

What are those "clear differences"?  The only "clear difference" I have seen is 20 MP vs 22 MP, which is insignificant.

How do you know that?

I would be impressed if anyone could see a resolution difference from a 20 MP sensor and a 22 MP sensor, of the same scene with the same lens and settings, and displayed at the same size.  Are you really claiming that you can see a 5% increase in resolution in a photo?

In any case, please tell me what you know about the 6D sensor other than it is 20 MP as opposed to the 22 MP of the 5D3, and where you got that information.
