"clearly actual horses" is a strange claim when all ponies are actual horses.

Suggesting they are different breeds of horses is also strange, since the show doesn't mention any other breeds.

Princess Luna appears very similar to the other ponies. Her sister must be the same breed as her. Without any further information, we'll have to assume the princesses are ponies, and their size is attributed to their powerful magic.
