Because of the Steam Link app, it's better at streaming good video quality than my Apple TV. I was really surprised by that but the app on the Samsung TV is wayyy better and doesn't drop half the frames.

I just allowed my Samsung TV to connect to the wifi (to access the local network, because the Steam Link client is better on it than it is on the Apple TV) and then, on my router, I blocked all Internet access coming from the mac address of the Samsung TV.

I don't think it will ever happen, they are sold to the motherboard and their efficiency probably depends on that.

However those TVs are not easy to get and, like you said, they come with an increased price.

I couldn't recommend enough to buy an Apple TV (or equivalent) and block all Internet access to your "smart" TV. I did this and everything was instantly better.
