I voted "no bar" but, as others have pointed out, it doesn't look right if it is simply removed. The crease works better, but I wonder if cutting the sharp corner of the remaining frame on each side wouldn't also help. That would create two creases.
Here's a crude paintover to explain the idea:
Proportions to be tuned by an artist.
As always, I assert that the frame itself, particularly the thickness of it, is absurd. It's just wasting space on the screen. Go with a faceted, seamless canopy and you'd still be consistent with the ship's design.
