It was probably an appaloosa. As you most likely know, appaloosas vary in patterns, some can even have symetrical spots. It maybe could have been a dapple but they're easy to spot.

She appears like a blue roan that's actual roan on a black coat. The mane, tail, head, and legs stay black, mutually as the physique takes on a grayish or bluish seem. Blue roans are on occasion flawed for gray or Grullos. Grulla and Grullo is an identical coat shade. Grullo is the main uncommon shade of quarter horse horse registered with the yankee Quarter Horse affiliation. A Grullo is a black horse with the dun gene. Grullos ought to have Black or Brown Legs, the pinnacle would be darker than the physique, dark information on ears, a very different dorsal stripe that runs totally from the backside of the mane and into the tail. Grullos could on occasion have stripes on the legs, mottling on the better legs, shoulder, gaskins, dark rings around the ears, striping on the brow, and stripes crossing the back shoulders, or neck.

This sounds like an Appaloosa with a reverse snowflake pattern. This is white spots on a colored background. It may have combined with leopard to give an all over spotting pattern. Wish you'd taken his picture!

I have never seen a black horse like this but I have seen a chestnut and this was caused through a bad case of ringworm. Wherever he had the ringworm the hair grew back white.

It sounds to me that the horse was either a Snowflake Appaloosa (Reverse Leopard):

Or maybe a black horse with Birdcatcher Spots:

The easy way to tell if it was a Snowflake Appy (Or grade Appy) is by the mane and sclera. Not to mention that most Appys have mottled skin around their eyes, muzzle, and butt.

Hope this helps! :)

This is just a guess as I have never heard of anything like that and your question isn't really in my comfort zone :P here's my best bet:

-Maybe it's genetic? Like white Bengal tigers? Don't know if that's possible but -shrug- just a guess :)

-It could be that the horse was painted?

I am guessing that what you saw was an appaloosa. They are well known for having spotted coats.

leopard appaloosa

Did he look like a dalmation? If so he could be a Knabstrup
