I've brought the faint-defect lesson from our FR10 work into this FR5 review: confirmed parts first, not prettier pictures. Here the bright streak changes when the bezel is reseated. Should I start with the holder comparison?
My cover crops hid exactly that: two different stops touching the part. I kept staring at the stripe while the seating difference sat outside the picture. Get the holder designer to look at the full views with you.
Then include both identified bezels when the seating arrangement is reviewed and in the later lighting comparison, because a repeatable holder still has to give the camera a view of the real faint defect
