I got a 8 year Samsung low tier TV which doesn't even have Bluetooth but supports installing the Steam Link native app. On the other side, I also got a 2 year top tier LG TV which doesn't. This seems a joke, almost a disrespect towards the LG customers. The Stadia native app got added to the store and now it's closing. You should have added Steam Link, Xbox Game Pass or even Moonlight.
This is more a shame call than a wish...
