@CursedSilicon This *may be better than what upscalers in TVs were doing and *what early generation unscalers were doing [sorry, fixing some serious editing malfunction there], but on eg bar TVs, I've been just completely distracted and fascinated by the phantoms all around the edges of where the picture is noisy or busy. You really don't notice them at first, then you start to pick up on just barely perceptible artefacts... faces appearing in the grass in football matches... things like that. But MST3k has a lot less high entropy moving texture that lends itself to that so it may be fine for that reason too. Maybe the seller has original video? From an ethics standpoint, it was likely trained on imagary gained against consent and through abusive scraping, or I'd assume so unless proven otherwise, but it isn't trying to create a creative work that destroys communities, so there's that at least. Good luck in your pursuit!
