So it works for me. I use the app on my computer when I watch films on my PC via the Samsung 95B 65 inch. Unfortunately, Ambientlight only doesn't work with the streaming services Netflix, Prime and Disney. For Samsung TV there is the App 129€ or the Sync Box. Otherwise everything else works.

Yes works

Yes, but I also have the Hue Play HDMI Sync Box and a Hue Bridge. Then it works for me with absolutely everything on the TV (games, streaming, etc.). I'm not sure how and whether it works otherwise.
