i had my front AND rear bumper repainted. (from accidents)
For the whites, the color contrast and difference from the OEM is pretty bad. My back bumper is darker than the rest of the car. My front is a bit lighter (and hood as well)
And not to mention, it may look good, but the qaulity SUCKS. (the rear was done by the dealer - the front was done by a reputable auto-body shop from my Insurance agent recamendation)
The rear bumper, I just dropped a droplet of tar remover to get rid of some tree sap, took the damn paint right off. My front bumper paint started flaking off after a year, so I bitched and they repainted it for me free.
I hope your quality is good and lasts for long time.
time will tell, so far, looks much better than with the bugs.

how many miles you have on it?
