Are youtube videos enough to display current game image fidelity?

i don't know if pro channels have access to higher bitrates or quality, maybe so, or it only depends on the nature of the source video, but what i know from my personnal experience is that all my uploaded PS4/PS5 videos are butchered by youtube compression, and look a bit worse than actual gameplay.
Screenshots fare better though.

 

I vote other. On my 1080p monitor I tend to run YT at 1440p where available and it does a job of making it look a bit better than a native 1080p stream.

A 4k stream on my 50 inch tele at 3m looks alright.

Both are ok. Neither are brill.

If I really want to post an opinion on a games visuals on a forum I resort to a 480p stream on my 6 inch phone.

 

Even the video from DF patreon are not enough imo, so... I mean, sure it's enough to have a good idea. But it will never be like playing the game, or course.
