Yes, I did it. TV is mounted on a white wall, eye level about 1/3 down the screen when on the sofa.
I’ve got 24v LED strip along on the back along the top and down the sides. (centre speaker is mounted below so didn’t put any there). You want it dimmable so you can get the light level right, and supposedly daylight colour temperature for best colour rendition (mine isn’t but it’s not super-warm).
It’s definitely better to watch when its on, even if you have other room lights on, and ensures you don’t have any lights reflecting in the screen. Its a plasma so black level is very good anyway but does seem to improve colour/contrast and detail (you have less ambient light from other sources bouncing off the screen)
I’ve seen ambi light in demos but wasn’t convinced.
