R6 color noise issue?

I have been an R6 user ever since it was realeased. Before that I used a 1D-X. Although I have been mostly satisfied with the R6 in terms of image quality, I noticed immediately right after the switch that R6 handles color noise just differently. It is hard to describe, but I have the notion that it produces much more color noise, especially at higher isos. I'm a wildlife photographer and I tend to see a lot of weird purple colors, sometimes greens in the out-of-focus, otherwise diffuse background, which is really bothering me until this day. I never had anything like this with the 1D-X.

Anyone else noticed this?
Thanks for your input.

Regards,
Adam
