Got a WS1812b Stripe with WLED on a Esp led-strip-board/).
Now i got a new tv and thought about selfmade ambilight.
So Hyperion NG installed on a RPi 4 with Hdmi Splitter, Hdmi Grabber and cabled via Apple TV to the tv.
Without setting up the LED Kontrast correctpy, the leds gives back the screen collours.
Since i read here about other stripes and setups, i wanted ask if my setup is useful or totaly rubbish. 
Thanks!
