My FR10 comparison already taught me that less glare can hide the faint scratch; for this UR5e bezel set I've kept quality-checked parts, but the image labels still follow moving highlights. What should I retain?
Keep the identified parts and full source images, with their capture conditions. Exclude unsupported scratch labels from tuning, but retain their history so the next person can see why the working set changed.
Then compare its repeat presentations alongside an accepted difficult surface, keeping the part identities attached to every capture. A set of obvious scratches alone will give you a very comfortable but incomplete answer.
Can the next loader tell when the bezel is seated correctly? I do not know your holder, but a small unnoticed tilt could keep making new-looking examples.
