On the contrary, the dark tones cannot as a rule be "cleaned" without ill effects. Consider for example the hair of the girl in the example to which I link below.

This comparison is not done with equivalent settings. If you equate the total light (assuming the same scene lighting), things go back to their places. The OM-D is slightly worse, detail vs. noise, like here, here and here, and maybe has some deep shadow advantage here to the A7 only but the A7 is more detailed. The 6D beats it every single time like here (can you read the text?), even in the deep shadows. In the greens (what DXO measures), it seems to be doing OK. This is in artificial light, and of course reflects the color filters, etc.

So the real world results seem to show that the OM-D shows more noise vs. less detail, even in the deep shadows, with normal processing, at least (and no sane person will try to pull the shadows in those cases anyway).

Now, show me your calculations to prove me wrong.
