I have a somewhat opposite experience:
LG C9 OLED:
Netflix on Apple TV - completely unusable, TV shows are a total blur to me
Netflix on PS5 - fine, I honestly don't get much strain TBH, and I can totally follow what's going on in the show. However I can notice dithering flicker if I look really close up at the pixels, but doesn't seem to affect me in a TV context.
Both inputs are4K, no HDR, set to filmmaker mode and all possible post-processing effects and color settings are ALL turned off, plus disabling deep color and enabling 4:4:4 passthrough
