Did a paint oven damage my car

hi guys, new here, I signed up cause I need some advice

I took my car to a shop for some damage on the door, the door was repainted but the whole car was put in the oven and when i got my car back it had some weird discoloration on another part that was not painted, is it possible that this is damage from the oven? should I ask the guy to fix it? thanks in advance guys, I will add a photo so you can see for yourselves
