Well, bad 4k killed 4k.
I honestly don't care a rats butt about any of this.
I did for a while, even got my 4k tv pretty early, hot bluray 4k too ( which died prematurely and got replaced by the cheapest thing in amazon).
Oh I used to look for that hot 4k movie to see in my hot 4k tv, only to see hot garbage.
Crap, just high bitrate garbage. My tv has NEVER been pushed to what it can look like. Perhaps, I only remember a good sharp 4k bluray being '' The Meg" which is an absolute garbage movie in turn, but I may remember it looking sharp.
No streaming didn't kill squat, having no standars in quality killed things. There never was quality above.and beyond a very good dvd, no one bothered to force it, studios never talked about it, they did the laziest, cheapest crap imaginable and pumped out their garbage. Streaming just did the same without disc. If anything streaming is poised to save for 4k as more material is likely recorded as such and just shoved into the server like that. I may pay for 4k netflix one day, ISPs gave up on caps at least for my area.
Dude is living in la la land and is obviously not a regular customer. Perhaps he doesn't even watch TV or has some crap in his house no one has, huge projector like a cinema and such.
