Can Apple TV app substitute Apple TV 4K?
I have an Apple TV HD and I recently purchased a 4K TV.
I assume my current device will not support 4K content, however, I have the Apple TV app on my Samsung Smart TV.
Available 4K content on the app will playback as 4K, correct? Are there additional benefits of getting the Apple TV 4K hardware even if I already have the app on a 4K TV?
