You may have addressed this previously and I just missed it but the banding on either side of the the Commadore braid was different than the standard braid that we see on the other uniforms. It was more of a sine wave. You can see it in the above screen cap links that you posted. Here is a photo of what I'm talking about
Again, if you already address this just disregard my comment.
EDIT: Nevermind, lol, I see that you HAVE addressed it. Sorry.
