Banshees are from Faes / Elves familly to begin with even in real life folklore so I guess you could put them as half ghost half elf, they seem to have evolved in medias recently (mainly manga and such) to represent Death Elves too, aka they keep a body so you can remove the ghost part and go for the necromancy route, which is the path KC chose to take, keeping the ghost elements as parts of her dress design.

So long story short, them being immaterial or not depends on the universe they're represented in.
