So what's so special about Astarion again?
In most settings i know Dhampirs are unable to make offsprings ...
(Dunno about DnD tho to be honest.
)
Vampire Spawn can still (theoreticaly) become full Vampire and start making offsprings.
I gues that would be main difference.
//Edit:
Oh! And he cast no reflection!
That is also usualy something Dhampirs do.
