I'm curious why you would want 4K in this case? I was over at a family member's place and threw on an episode of TNG to kill time. I was trying to figure out why everything looked so cheap: Picard's uniform, other costumes, the alien makeup. It was because they'd increased the definition past what the sets, costumes, and makeup were designed for. Personally I prefer the fuzzy look which appears more 'realistic' to me.

I saw a fan-made AI 4K remaster (Star Trek Borg) and it was a lot better than the remastered Star Trek on Amazon prime.

I think the AI adds crispness that was not captured due to limitations in the cameras (and skill of the cameramen) at the time. Possibly it also fakes textures to make them more visually appealing.

This is a good point, but AI also will allow us to enhance the video in other ways than upscaling, such as inserting (or replacing) CGI / special effects. We should be able to really up the visuals.
