Lox, I haven't been able to verify that any of the differences that I saw on the ship in the video couldn't be accounted for by night vision technology. The biggest one is the absence of the name of the ship where it should have been. But the letters of the name are blue, and it looks to me like some colors are not able to be shown in video that comes from using night vision technology. Same with a yellow stripe down the side of an upright part of the ship (can't remember what it's called) that is also missing. So I'm not going with the sister ship idea that was suggested in the video that I saw.
