Apple's default video players are severly lacking in almost all of their platforms. Try to open an mp4 file you downloaded on your iPhone or iPad and you will be presented with one of the most atrocious "players" ever.
But that's because Apple has never cared to support on-device video viewing on their mobile devices outside the gallery app. They think people only use streaming apps and websites to consume videos so they haven't bothered with it.
I'm sure we will get VLC on the Vision Pro or something similar that will take care of it. Platforms that publish 360 content will have to distribute their own custom solutions
