I would be very skeptical because the display surface of the door always seems to be kind of toasty warm. These doors are brightly lit; they are a lot of pixels; each door has the equivalent of a computer and a couple graphics cards in them. I believe that the doors even have active cooling fan vents on the sides (the doors are something like 3 inches thick!). None of this says "power savings" to me.
