I've still never heard a virtual trumpet that sounds like a real trumpet. Not even close. Each trumpet player has his own tone or "lip" that is unique. I can tell who is playing just by a few notes.
Solo I don't think there are many virtual instruments that get even close to the real ones. But grouped together, mixed with real instruments, it gets a lot harder for the untrained ear. Especially in a context like a movie where the music is not the primary focus and often much less nuanced.
