I am their lot guy. This is factory. This dealer often asks me to look at the results of a local shop on bigger stuff. Look at new cars on the road. There are a lot with striping. Amazes me.
The Camaro is due to the panel angles. Chevy had to send an explanation letter to dealers to show to customer's that questioned the difference.I had one vehicle that needed a rear bumper and quarter. after spraying everything and putting it back together the bumper was a different shade. Thinking that mabey there needed to be more color put on the new bumper I took it off and had the painter re-spray it and when put back together it still looked a shade off. Had me shaking my head the only thing I could come up with is the difference in the angle must be just enough that it looked slightly off.
Look at any new Camaro and the Qtrs. look different then the doors especially Silver, shows up like a sore thumb.
I also had a 2020 Impala that had sanding scratches as if they were denibbing at the factory. Dealer said he sees that often.that looks like they need to adjust the robot to get better coverage but the Manuf. don't care in the least and 90% of the retarded public don't either and never see it until we have to fix some damage then we had better be spot on cause they know the car and it never looked that way or fit that way when they bought it.
