Haha. First off PS1 games were made with CRTs in mind which don't use pixels to begin with so a 720p or 1080p screen would be terrible. Which lets be real. Outside of hardcore enthusiasts the average person isn't going to have a heavy CRT in their house.

And actually 4k oleds are great for emulating CRT effects with CRT Shaders over lower resolution non CRT devices and more resolution would make the effect better.

And film actually...

35mm film is thought to have a digital resolution of 4K, whereas 70mm Imax is closer to 12K and 35mm Imax film has a digital resolution of 6K. Most movies will be edited and colored and enhanced digitally, regardless of how they were shot. (Called digital intermediate and usually at 2K resolution). Even Imax projection systems cannot play back anything higher than 4K, even when certain movies are scaled back to a digital or film print for distribution.

So yes old films on new TVs are definitely closer to the cinematic experience in theaters than CRTs. Not to mention the wider aspect ratio of films leading to content not being cut like they were for old TVs.

Not sure why you are so resistant to the idea of using better technology. If you are that resistant to 60 fps+ and higher resolutions you can stick with it, but other people will opt for the better performance and visuals if it's an option.
