Good that you mentioned about recent versions.. yeah just tested on the 2.4 nvidia and 1.2 intel and works well..
The wall maybe it's not the best example..
Recently I had a render with a girl with freckles or body hair.. you know.. some small skin improvemets but at the end it will make a big difference.. on wall nobody gives a shit.. anyway some body hair or freckles disappeard on the nvidia or make it to look weird..
PS: nvidia left, intel right.
More black lines on the hair and makes hair a bit more real and more detailed
Wall again it's missing many paint bumps .. not sure how it's called in english.
my ideea was: nvidia does a good job as well but hides lots of texture details that you won't wanna miss in some renders.. maybe not in this particular one.

Anyway.. I'm done with this:
It's another 30 mb plus.. add the addon, wait another 10 seconds.. you get 2 denoised renders and use the one you like
