I imagine most labels have the final say in the matter.

Also, even if artists could take themselves off the platform, I'm not sure that many would. It has the largest market share for music streaming, and it isn't even close. The artist would be losing a ton of potential listeners and a huge opportunity for new listeners to discover their music.

Furthermore, while Spotify notoriously pays artists much less than they're worth, they still make some money from it, as opposed to no money. Sure, artists could tell Spotify to shove its pittance of a payout up its theiving ass, but what do they get out of that? Maybe a few existing fans buy the album off Bandcamp when they otherwise wouldn't have, but how many? Would those sales offset the loss of revenue from streaming? I'm skeptical.

It really depends on your viewing distance and the size of the display. If you're sitting 15 feet away fom a 55 inch TV, the difference between 1440p and 4k is going to be a lot less noticable than when you're 2 feet from a 32 inch monitor.

Just keep in mind that those targets are with FSR.
