Indeed there will always be a small difference, plastic body parts on my car aren't painted the exact same hue as metal body panels either, but OP's car is in a whole another league, I'm glad GM agreed to repaint the front.
(Interestingly, I have a new front fascia and the doors blended due to a, khm, mishap, but the color match is absolutely perfect with the rest of plastic/metal, respectively, even though the body shop obviously used a different batch of paint, from >12 months later than when the car was built. The color difference on OP's car is way worse than anything I've seen.)
