My 9/16 build was delivered with a bad paint job on the front bumper. They had to remove and repaint the bumper. My car was basically a Q3 16 rush job as they were pushing very hard to make some sales (delivery) goals by the end of that quarter in order to make gaap profitability (or something).
Anyway, your thin paint areas look just like those on my bumper before they repainted it. Mine were just in more noticeable areas. Definitely take it to a SC and have them look at it.
If they give you some crap about how their robots don't miss spots just send me a PM and I'll give you my VIN. They can look up my build and see that there is indeed a precedent of thin paint spots on a bumper and the solution was to repaint.
