To be fair, that’s not the only reason the TV app was created. Most notably:
– Users want a single place to keep track of all the shows they’re following across all services. Streaming services weren’t coming up with a cooperative solution for this, so Apple did it instead.
– Plainly put, a large chunk (if not most) streaming service apps suck. The TV app adds value by letting users skip the choppy, inconsistent, badly organized, lowest-bidder browsing UIs so many streaming service apps have and get straight to watching this week’s episode.
I like the TV app and wish it did more. I wouldn’t be bothered if I never had to open a service-specific app again. All I need is a clean, frustration free way to browse the libraries of the services I subscribe to.
