I have noticed the micro scratches in recent models as well. I keep thinking, maybe I’ll start using a screen protector but while you can see them at angles when lit, it hasn’t been noticeable in normal use.I’ve never used a case or screen protector for any of my iPhones, dating back to the original. Never had a problem other than minor screen scratches in the last few years (screens have been getting softer as they are being made to be more shatter-resistant).
Gosh you are wilder than me. I love the look of the device as well it’s gorgeous but if you happen to shatter the back of the device it’s considered a total loss at Apple.I use mine naked. Only have a screen protector on it. No AppleCare.
