Not OP, decided to look up an old Sleater-Kinney music video to do my own comparison. It appears to be a case by case basis and a lot of bands like Paramore and Muse didn't opt in.

Whatever AI upscaler they're using seems to mainly be focused on removing artifacts and making hair look better. It literally does not add any detail to the video and at times you can see very subtle warping during scene transitions. So in addition to ruining the original upload it doesn't even do anything.

I mean really, this image should speak for itself. Yeah, it's a decent way to fool people into thinking they're looking at an improved image, but you're just polishing a turd. There is no way the computer screen would still look like this at 1080p, it's just not possible.

Oh and the best part is I had to go to Vimeo to grab the top screencap. It doesn't exist anywhere else.
