You call it nitpicky. I call it a meaningless distinction.

Dark matter is no more or less a theory than Darwin's Descent with Modification.

Darwin's theory needed to be modified extensively to deal with genetics. And modified again to deal with paleontological evidence on how speciation works. And modified again for jumping genes. And modified again to cover things like having a virus create a new clade of Mammalia by hybridizing mammals and a parasite. And yet we still talk about Darwin's theory of Evolution.
