Nah, the Netflix iPad app already worked fine in the Vision Pro Beta, according to people who had and still have it installed. Sure, they could do an app specially done for visionOS, like Disney did, and that'd need engineers to do. But atm, they are actively worsening the Netflix experience on Vision Pro, by opting-out of making their iPad app available.
It's very relatable, though, that Netflix - and Spotify - are showing Apple the one finger salute after their repeatedly abusive business practices. The Vision pro shapes up to become another media consumption device like the ipad - at least in it's first iteration - where it hurts Apple if they get snubbed by big content providers.
