I hope it won't be offtopic if I mention base S23 (not ultra). So I had the impression that the color reproduction was a bit below my expectations. What's funny - standard wallpapers are great to present this problem, it's a really good benchmark.

So I set the blue planet (attached) as a wallpaper/lock screen on two phones, my old S20 FE 5G and new S23. On S23 gradients are not smooth. Period. It's enough to tell if the panel has good color reproduction or not. Same wallpaper on S20 FE 5G looks better (S23 has worse color reproduction). I don't have a third phone to take a photo of how it looks.

Ps. one minor thing to notice; when I wake up screens, both displays perform comparable and in both cases gradients on wallpapers do not look smooth, but after unlocking phones it changes. S20 FE 5G seems to render nicer colors and gradients become smooth. On S23 though, gradients are still not smooth (looks like color palette limitation or something). So I don't have a clue if this is hardware or software issue. I have only few days to decide if I return S23 or keep it.

Pss. I checked the webp file and it's perfectly fine, it looks super nice on my MacBook or my external display.

It may get fixed with updates. S9 had an issue with banding it's called and was fixed with software update
