So, the other tail is called "waves" I believe, and clearly looks like waves on the tail. I suspect that it is JB's first etops aircraft. Possibly for Hawaii? I don't know. But I'm guessing it's an etops NEO to begin the flight portion of etops certification and possibly be used on future routes requiring etops other than London.
Total guess.
