Time to revisit a question: Should I have my hood repainted

A few months after getting my S4, I caught a rock of some type when passing a construction site in New Haven, on a local street. I left a small dent about the size of a green pea in circumfrance, and about 1/10th of an inch deep. It also scratched some paint off in the surrounding area which I had touched up with the same color of my car (dolphin gray).

However, I am at the point where I feel the blemish is lessening the enjoyment for me of my car. I've had quotes of $500 and $405 to have it filled and the hood repainted and coated with clear coat. The question is whether or not the newly painted hood will match 100%. I've heard yes, and yet some people say a good eye can tell the difference. I have a good eye so I don't want to be worse off and $400 poorer for the effort. Its hard to believe its impossible to have this hood restored to 100% factory appearance, does Audi have certain body shops that are gauranteed to match paint?
