wow.. that's a nasty chip

I wouldn't use the touchup that you got at the dealership. Those paints are normally very thick and difficult to get into the chip without it blobbing. Go to a good local paint shop and have them make you some properly thinned touchup. I think that chip may be to big as you've said though. I don't know if you're going to be able to have it look perfect again, but certainly it will look better than it does now
