I understand what you're saying and it's true that in many cases denoiser works rather well. I use it from time to time for the background. But when you render in 4k with the camera close to the subject I can see the loss of detail as

now it's obvious that for VN/comics it would be a big waste of time to render everything at 10000 iterations.

Regarding the Noise degrain filter, in the few tests I've done I've noticed that it works best on high resolutions and in complex areas like dark zones.
Ah, I noticed that you used the INTEL DENOISER. I tested it and compared it to the Daz3D's denoiser and the Daz one is MUCH better. I didn't like the Intel one at all and found several problems with it. I recall posting tests with it in this thread a few months back in fact. I also only denoise on the last iteration. And I NEVER see things smoothed out like you have here. But, to each his own.

Another random denoise versus no denoise test... one of these two images was rendered with 400 iterations and denoising. The other was a full render, no denoising using default settings. I used a 1.00 pixel filter radius on both. The full render took me over 22 mins. The other denoised one took just over 7mins. Both were 1920x3162, resized to fit this... I would rather use denoising rather than wait an extra 15 mins. Grant it, if you're doing some 4K image and you have the video card and patience, go for it, but... I do 1080P images and there just isn't enough of a difference to justify 15 mins. I was going to go for 800 iterations for the denoised version but I wanted a more extreme example, plus I mostly use 400 and rarely use 800 iterations.
