The information provided in this paragraph is sourced from Mark Gurman of Bloomberg, who reveals that Apple is set to release a new Apple TV app that will combine all entertainment content into one app. This update is expected to be available around December.

As for iOS and iPadOS, the iTunes Store app will undergo changes, with movie and TV show categories being removed and the purchasing capabilities being integrated into the Apple TV app. All of these updates will result in a much clearer and comprehensive video streaming experience on Apple TV, with all content being consolidated into a single app.
TL;DR: Apple is creating a new Apple TV app that will merge all entertainment content into one app, improving the user experience and offering a unified streaming platform.
