Polished-cover scratches with no agreed physical reference

Our FR5 inspection proposal has a folder full of cover images and arrows. Some arrows point at a streak that shifts when the cover tilts. The filenames sound much more certain than the pictures. We still have the covers. I want quality to check the actual surfaces and identify accepted and rejected examples before we pay for lighting changes. Or rather, before we decide the light is the only thing wrong. What should we retain from the current pictures when the seating was not recorded?
