Am I seeing it right... It looks like in the front there's 2 large well defined white spots out around the shoulder blade area, then another more diffuse looking one in the middle at the wither area. I see the 2 smaller white dots on either side of the spine in the middle of his back pretty well.
That's just glare. There's no white in the center wither.... just the large white spot on his shoulder blade and the two by his spine.
