Yes, we get an ARCW - an ADS Route Conformance Warning.
The controller is supposed to query it because it differs from the cleared route. If the pilot doesn't amend the route, the alert has to be coordinated to the next sector prior to hand-off.
We see quite a few of them on acft coming from the Eastern States as pilots try to anticipate the STAR they'll receive. It isn't a problem, except that a prominent yellow line of the non-conforming route is displayed on the screen which we can't remove and it can make the screen look quite congested.
