I had for my Packard as well, but I'm trying to avoid the labor to try and match perfectly.
Last perfect match (as perfect as possible for a NLA, non-cataloged paint) for less than 10 oz was about $700 which in my mind is a fair amount for a body color with that many spray outs to get to the match.
I don't trust that I can scan the "true" existing color to even have a foundation, so I see a like bill, with limited results, which I'm trying to avoid.
Would you be willing to share the mix that your shop came up with showing the colors/percentages to create the engine paint?
