Hard to say how visible that is, the pics are distorting the appearance. But it looks like no matter how carefully you touchup the damage it'll be big enough to attract your attention as you walk up behind the car. And from five, six feet away.

And yes, a pro shop. Stay away from the dealer with paint issues involving anything but warranty claims.
