I don’t really think going higher than 1080p really does much for a movie, after that point the finishing returns start to set in unless you have an absolutely giant TV or you’re sitting super close to a still pretty big TV. Maybe for vidya games or something it could make a difference or something filmed in native 4k could potentially look a bit better but especially for something being digitized from a film negative, it can be a choice between keeping analog grit or smoothing it all out digitally and I’d prefer a movie shot on film to continue to look like it was shot on film.
