that's not the point - they were saying that retroactively going back and viewing old content on 4k, you can easily spot the CG/issues etc.

ex: Farscape - all the CG was rendered in low res, so even when you view a 1080p copy it looks silly. Imagine all the content that would have to be re-done and upscaled to make it watchable in 4k.

It still seems like it would be better to try to reproduce the original experience by viewing it at the original resolution.

Good luck watching movies in NTSC or PAL, I for sure don't want to be watching movies on a 720x480 window.

Are you going to keep a CRT TV running in your house to do so?

No, but I wonder if there is a good way to emulate one?

Most SNES emulators have a mode for this.
