App Store now mentions when iOS apps have Apple TV versions

Update: The feature now appears to have propagated correctly, as the codename identifier is no longer visible. The app now correctly lists ‘Apple TV: Yes’ in the description for universal apps that support Apple TV.
Apple is rolling out a way to see if an app in the App Store also has an Apple TV version. From this morning, App Store listings have included ‘SF.UniversalAppleTV’ labels. If present, it means that the app in question also has a universal Apple TV app available in the tvOS App Store.
Evidently, the feature is not fully baked and is in the process of rolling out. The label is clearly an internal identifier not meant to seen by the public. When the feature is fully rolled out, expect it the left column to simply say ‘Apple TV’ which matches the language used for Apple Watch compatibility.
