Yes but Apple has stated that it’s a special program for video subscriptions that other developers can and has joined even before Apple (eg: Canal+). The terms are not public but it looks like they’re made available as an option to developers that have apps in that market. It looks like the discount is available if your app implements all features in the Apple video ecosystem (AirPlay2, Apple TV native app, etc.)
