I feel like I need to start doing a systematic survey of 3D horses in fantasy anime...

I've not compared screenshots from any shows yet, but I am CONVINCED they all basically use the same 3D horse model. Is there like, a 3D outsourcing company that specialises in really bad, but cheap 3D horse cuts for anime? and every production assistant in the biz is like "oh we need a horse shot we better get 3D HORSE DONE QUICK .CO. LTD on the phone quick"?
