Yall are talking about the actual eye? I thought yall were talking about white hair and I didn't see it on SL.
No the amount of actual eyeball white that shows on Sara Lee is more than you'd see on a QH-Paint type, or most types... Usually you would see only dark, unless they are all stressed out.
Appys are unusual in the amount of white you see in their eyes, it's one of their identifying traits.
Appaloosas have white sclera around their eyes, like human eyes. In appaloosas, it completely surrounds the eye and is an appaloosas characteristic unless it's on a bald face. I think sometimes horses with bald faces have white around the eye also.
