Where did you get the 4K version? Even a 2K Bluray has not yet been published.
You got me doubting myself, so I checked!
You are partly correct, there is indeed no official 4K version released yet, but there is a Director's cut Bluray, has been available for some time.
You are welcome to my version! it is not HDR (obviously), but it is super clean.
I also have Alien and Aliens, old classics such as Ben Hur, Fiddler on the roof, Spartacus, 2001 . . . . .
All upscaled and enhanced using Ai.
All in 4K. a few in HDR (if the original was HDR).
PM me, if you want any.
Meanwhile, some screenshots in 2160p, feel free to zoom in:
