Or maybe it's like the Philips Ambilight+Hue, that people swear adds immersion by letting content color the environment around it.

Lol, adding a hue is usually a crutch for a too small screen with lifted blacks... which doesn't paint the pro in a very positive light!

Ironically by adding a gue to a nomral screen, you're effectively 'adding' pixels to the display... unlike the pro which wastes pixels on the 'hue' because many of them are not in the ideal viewing angle.
