The different breeds of horsez

Honestly, I've tried the game with each breed, and I haven't seen a difference in how they move, how they respond, how well they do, etc.

It seems that it is only an esthetic thing such as how big the horse looks in comparison to the rider. This would be similar to the fact that you can change the color, and shape of the saddle. For me, this is disappointing. I would have like that the Arabian would have a certain attitude/movement that you would see as classically different from a French Saddlebred.
