So you haven't seen the film in 4K, but you know it looks worse?
It was shot on 35mm film and displayed in both 35mm and 70mm. The resolution of 35mm is approximately 6K, 70mm is enormous and requires special projectors. It 100% was meant to be seen in that level of detail -- and more.
The "Soap opera" look is from the TV, not the film. It's a setting trying to replicate a higher frame rate and is what most shops switch the displays to in-store. Switch it off for a proper cinematic look.
