2) They don't mention Vision specifically but they do tag content with HDR10. Not sure if they lump it together or if they simply opted to go for hdr10 over vision because licensing.
3) Pretty much all old cartoons are on there, both Disney and Marvel. It has the 1979 Spiderwoman show that surprised me. Random viewings showed them all to be crisp and clear.
4) Who Framed Roger Rabbit which I guess is technically Disney. Also a lot of NatGeo nature shows. Also also apparently there's a "live action" remake of Lady and the Tramp that's specifically made for streaming I guess?
All Marvel Saturday morning cartoons which I forgot all about. The speed at which they release feature films, ie Capt Marvel and Endwar is already on there.
The bad. Their tagging is currently all over the place. For instance there are categories a la Netflix that show a lot of content but not all (like the 4k one) which makes you think some content isn't on there. Case in point, it shows Cars and Cars 3, and you explicitly have to search for Cars 2 for it to show. Also no Spiderman Homecoming or Far From Home
