Its NOT resolution, is mastering and whatever else makes a quality image, period, end of story.
Every single time, resolution an effing gimmick.
Crap is crap at 16k, 8k, 4k, 1080, and 720p.
And most material and whatever they do for video is borderline crap, dont get me wrong, i am happily entertained with all the garbage I consume, but on the rare occasion I have seen better curated contents image quality wise, it is like ahhhhh, oohhh, you know celestial sounds and all that, ive seen this at 720p, and 1080p, i dont even remember what movie/ program it was, i just remenber thinking, what hell, a DVD can look this good all this time? And then same with blu rays, its all mostly crap, not showcasing capabilitilies, at any resolution.
Its cause, whatever they do editing, mastering , whatever, probably costs lots of money. Probably will always cost money even of they implement AI or some crap, AI will probably do a crap job and everybody will be like stick that 8k label and send it.
