Two people disagree about the same FR10 bezel mark

I need a common appearance check before I compare the proposed softer pads. Our polished cylindrical bezel looks acceptable to one person under the bench lamp and marked to another near the window. We retained the handled samples and an untouched one. What should quality define for the comparison, alongside the tooling checks for holding and clean release? I do not want to choose a pad just because its sample was viewed in kinder light.
