Comic spec is not only worth something for movies and tv shows. Some people actually do read them (crazy right) and like to have comic collections with their favorite characters in print format. So just because the TV show has already been made I wouldn’t say there’s no spec value, unless you equate spec value = tv/movie format.
This one is a different type of speculation, it is their first appearance in comic book format regardless.
