Yes, I have never seen maris ayin discussed in terms of milk after meat.
And on that topic:
My brother was at a wedding, and when desert was brought out, there was coffee and creamer.
The fellow sitting near him asked if the milk was pareve.
My brother said, “mistama”.
Fellow: Mistama? Mistama?
Brother (to himself): You ate the fish, you ate the meat. Mistama this is also kosher.
