I have an Optoma UHD65 4k projector and a 110 inch Elite Screens projector screen. The projector is a little older, I bought and installed it in 2018, but it typically has a gorgeous picture and I’ve spent years carefully calibrating it to my preferences.
The only other Star Trek 4k movie I’m unimpressed with on my setup is, painfully, TWOK, which has never looked great for some reason, no matter what version I’ve played (I have the original BR, the DE Remastered BR, and the 4k). On the other hand, TMP looks absolutely brilliant…like a brand new movie.
Yes the 4k TWOK, whilst a clear upgrade from my DVD box set wasn't anything special outside of resolution. The new TMP 4k though is spectacular.
