The 10BP4 in my RCA T-100 looked like that. The scanned area was visibly browner (or less blue) than the portion that was never scanned. Looked weird until I put the set back together and rotated the CRT to match the brown area to the CRT mask. In the second photo, I taped the CRT to mark the edges of those zones, which were more obvious to the eye than in photos.
