A pretty silly thing to ask. I can control my LG OLED TV from the YouTube and YouTube Music apps on my phone, as well as other apps, but the way that works is the apps hand off the stream parameters to the TV, they don't actually proxy the stream to the TV, which would have all kinds of drawbacks. The TV also comes out of the box or within 1 click of having the apps of popular services like Prime Video, Netflix, Apple TV+, Hulu, HBO/Max, Peacock, etc etc all of them they're just lightweight javascript applications.
