All the points against Bluray in this thread apply doubly to the UHD format that so many tried to claim the PS4 Pro would fail if it didn't support. Bluray was only utilized in game systems because of higher capacity discs. That's it. It wasn't the superiority of the disc format, and I doubt it was even strongly in favor of 720p and 1080p content seeing as HD only gained prominence due to the convenient nature of flat screens over fat CRTs in room arrangements. The exclusion here would probably be Sony since they tried to push bluray in an incredibly risky move that didn't really pay off with the PS3 launch.
Bluray only holds a small share of the market compared to even modern DVD sales, and UHD may as well not exist on sales charts in comparison. TV manufacturers are trying desperately to get people to latch onto 4K out of a distinct misunderstanding of what made HD big to begin with. Much like with HD, resolutions over 1080p will only gain prominence as manufacturers simply stop making 1080p monitors and televisions, and like with the resolution shift, DVDs will remain prominent due to their lower price and your average consumer not really caring if they can distinctly make out every imperfection on an actor's face.
I'm building a bluray collection personally, but I basically only buy movies when they drop to DVD pricing anyways. As much as I genuinely appreciate HD content, I still won't pay a premium for a format that is now a decade old.
