These were something that showed up in a very short period of time and the harness was used a lot but not for a lengthy period of time. They went away by the next summer when we clipped him again.
This is not common for the skin to repair itself, but it is possible. They are no big deal if they do not go away.
I agree with mini horse.
They MIGHT go away if the spots aren't that bad and haven't been caused for a huge period of time. The reason I know is that I had a heck of a time getting a western saddle to fit my short backed wide mustang. (In a lot of ways he is built like a Haflinger). Every 6 months to a year I would get a new saddle, think it's a good fit, and by the end of the riding season white "roaning" would start showing up in various places. One saddle would cause hairs at the back of the tree, the other at the withers, one at the rigging, etc.
But the cool thing is, when I got rid of the offending saddle and his summer/winter coat shed out, the white hairs would shed out with it. The only white marks that stayed were there when I bought him, from a cinch gall. But his back is fine.
So, no promises, but if the damage isn't too bad you might be pleasantly surprised this summer when he sheds out.
However, I do have a friend whose saddles caused permanent marks.
