I maintain an iOS and Apple TV app that share a bundle ID. We recently updated our Apple TV app to version 5 but iOS remains at version 4.6.6. However when you view the App Store Preview page it only shows the iOS version history and version number. Example https://apps.apple.com/us/app/trilbytv-player/id674488346?platform=appleTV
I believe this also has a knock on effect for MDM systems as we are aware of an issue where Jamf may not be able to allow Apple TV devices to update to v5 as the app store data it uses reports the iOS version number not the platform specific version.
