1) This is how appear the cr2 with zero adjustment

and this is the net from the D800:

Sorry but it is no true the the shadows are equally exposed. The 5D3 file is a bit underexposed compared to the D800.

2) This is what Mikael is able to obtain from 5D3.

and this is my result in 1 minute of post production with the cry from 5D3:

No doubt that the dynamic range of the D800 is visibly higher.
But honestly expose a photo in this way to save the highlights of a lamp that covers 1/1000 of a portion of the scene sacrificing the rest of the image I find it a choice absurd for a photographer.
In any case, it seems clear that Mikael wanted to obtain the worst from the 5D3 cr2.

Have you any doubt about it now??

3) The focus point of the 5d3 is different compared to the d800 file.

The portion of shadow shown by Mikael (an in my sample) isn't perfectly in focus on 5D3 file (the focus is a behind) and this isn't good for details. In D800 file the focus is ok in the portion of shadows.
