I would be surprised that DOS occurs that fast. Looks more like specks of one of your ingredients to me -- maybe droplets of a fragrance oil or bits of a botanical additive?
Awesome soap! Nice tiger swirl! I would vote on the oatmeal. Not sure when you incorporated it but I put mine in my batch oils and stick blend it so I know it's all blended. Ive had mine clump up before and it looked like yours.
