There’s barely any actual 4K content you can consume.

Ironically there actually is if you bother pirating content because that's the only crowd that will share full 4k Dolby Vision + Dolby Atmos/DTS-X BluRay rips.

Aside from that though, even 4k gaming is a struggle because GPU vendors went into the deep end of frame generation, which also coincidentally is the same mistake lots of TV OEMs already made.
