AFAIK one of the claims is that the doors are a net energy savings, because you can use better, opaque insulation material rather than glass.

And then there's the accounts of people opening the doors to see what's inside because it's faster, or opening the doors only to find out the product they wanted is actually not there.
It just feels highly unlikely.
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.
