word of warning though - there is a lot of funkiness going on in 8K screens that makes them not as sharp as you would expect. there is both spatial dither and reflections between different wide viewing layer films that make it effectively only about 30% sharper than 4K screen, rather than 2X as sharp.

still, it makes for text without jagged edges as text on a large 4K screen tends to have. so it's still worth it, just don't expect to fit 2X more content on screen. you will realistically be able to fit about 20% more stuff on 8K screen versus 4K, because of various bottlenecks like dither and diffusion i mentioned plus your own eyes having finite resolution too.

and if you're going to go 8K try to go to 85" or bigger. nobody ever regretted going too big on a screen, unless of course you end up homeless trying to pay it off.
