I've never seen this on any of the 3 Disney ships I've been on. The TV has always been on the wall opposite the bed/couch. Where did you see this video clip?
Here is a clip of 10658 on the Disney Dream.

That should be the same as 10158, just a mirrored version of it, and if the Dream and the Fantasy are the same..........
