Sure. I also simply explained what I had in mind and not. My assumption was that the images are processed in effectively the same way as far as NR is concerned.

Here are four crops. The smaller ones are the Oly, of course. The top row is processed with DXO Optics Pro, and the bottom one - with LR (copied from the screen of the link I posted). I equalized the overall brightness but that particular color appears darker in DXO.

Can you spot the NR?

6D (left) and Oly (right). Top: DXO. Bottom: ACR.

Clearly, LR applies more NR (or whatever you want to call it) to that color to the Oly than DXO. There is certain grain in the three crops missing from the bottom right one. Other colors are processed differently but I do not want to waste my time to post similar crops.

Here are Std. Dev. measurements for the four patches:

DXO 6D: 45.32

DXO Oly: 43.22

LR 6D: 40.55

LR Oly: 42.93

Lower Std. Dev. in LR for both cameras and the differences between DXO and LR is GREATER for the 6D than it is for the Oly.  Hmmmmm...
