CNXToonami did a side by side comparison of Jurassic Park in 4K Blu-ray vs 35mm film. It’s a bit cliché to prefer the old to the new by default (like vinyl vs digital) but the 35mm version looks really good here in comparison. In another referenced clip in 35mm, you also get to see the CGI dinosaurs and they look more realistic in this style.
Not all films look good in 35mm and, of course, they’re not made for it either but this is an example of good quality in an older format. I’d be intrigued to see how Jurassic World: Dominion would look, although we might end up with an 8K version by then.
