I don't know about other devices, but the PS4 has a unified "TV and Video" portal that I think tries to do something like this:

https://www.playstation.com/en-ca/ps4/ps4-entertainment/

Unfortunately, it's hobbled by the fact that the underlying apps are not reliable enough— Netflix works great, Disney+ is trash [1], Jellyfin has to be used through the browser so the interface is wretched. Not sure about Prime, Crave, and Hulu.
