I would keep after them. You will notice it every time you're in your kitchen (even if no one else does.) It sounds like the rep acknowledges that there is a color difference, so they should make it right. (You are not crazy!)

Even computer controlled batch mixing of paint can differ subtly from one batch to the next. The easy solution is to take one of your doors to a local reputable paint store and have them color match it. Have them choose "textured" rather than smooth for the match as it takes more than a single measurement and then averages them. It's more accurate than a single scan.

Then have a painter paint the molding. On the cabinet company's dime.

I know this thread is very old but did you get this resolved? I am having the exact same problem. The crown and doors came out of the same batch of paint. It’s driving me crazy

Fix your lighting. Things on different planes will always look like a different color, because they are lit differently.
