Yeah I'm not sold on 4k to be honest, unless you spend a load of money on the screen, most 4k monitors have a horrible HDR implementation as well so I'm still surprised to this day to see so many people talk about it.
I've got a decent 4k TV but it's not quite big enough for the distance I sit so I'm hard pressed to see the difference from a 1080p Blu-ray vs a 4k (although a good HDR implementation on the movie does make a big difference)
Ultimately, I don't care for 4k performance, 1440p is really where it's at and they don't quite wow me performance wise still, kinda feels like we're going backwards at times when you need to turn on DLSS on a 1440p monitor to play the latest games.
