Yep, xbox one x on insider ring then allows for game streaming via the console companion on Windows 10 or the xbox game streaming app on android. There are a few apps that will also do local streaming (official MS one also does xcloud) that can be sideloaded on Android TV... No dedicated app yet for any TVs but not hard to make as long as the device can pair with the Xbox controller or uses button combos such as back and start at the same time to emulate the guide... The Series X is so much faster that I'd imagine the encoder should be pretty top notch and therefore 1080p/4K streaming should be simple for it... hell even nviida gamestream can do HDR via the stream to an nvidia shield or moonlight.
