its already possible, but not really good atm. saw some scenes, where they changed the aspect ratio from 16:9 to tiktok. im waiting for that tool, google is working on. idk how it works, but it can guess, what should be outside of the image and the images i saw were pretty amazing compared to SD. 4k upscaling at 120hz also no problem, as i did this to the first season of spongebob and it really works fine with my hobby equipment in one night. id really love to see an upscaled 16:9 version of the it crowd and the first 6 seasons of scrubs.
