You are correct. All we are comparing is color depth, strength, gloss, and clarity to optimize the products final finish/coating.i know. i was just stating that you can't compare something rare as a lambo to a mass produced iPhone. Issues usually are cleared up on the following phone a year later.
All processes take place on a tight schedule with strict quality control parameters to maintain tolerance levels of heat and chemicals and improve unforeseen issues as they arise in a large manufacturing environment. We don't have time for next year, Apple's time today was already engineered years ago.
