Objectively, that is pretty true. Were they to flee Naboo in the Falcon (and we'd never seen the OT), it wouldn't stand out to me in the slightest except seeming slightly shabby for Royalty.
On the other hand, were Han and Chewy to fly the Queen's ship, it would have been great. A sleek, silver ship that blends in and reflects is perfect for smuggling. Now that I think of it, considering the fact that that ship would mirror the things around it, why doesn't it appear black in space?
