No, I don't think it's a sport.
The end product isn't being judged on athletic performance. Of course, posing is hard work, but that's incidental to what's being judged. To me , that's what distinguishes a sport from other sorts of competition.
As I said on another thread, it's a bit like comparing a show car event to NASCAR or Formula One. It's about 'show' and not 'go'.
For the same reason, I wouldn't consider chess a sport, or darts, or snooker/billiards.
