I should see what happens with my Philips TV if I block it from accessing the Internet. It's currently plugged in because it's also connected to my Hue lights but I don't really ever use any Internet features on it.

Also, if you really enjoy Ambilight, there's a (kinda expensive) solution to get it on any TV now: https://www.techradar.com/news/philips-hue-now-lets-you-turn...
