Yes, there are process differences between the two types of mask although there isn't a difference in the price. The matte masks seems to have a harder time to wet as there is a roughened surface on the finish, thus the ball is less susceptible to stick. I
I believe the glossy mask is a bit tougher so you have less of a tendency for the mask to scratch in process. In the market we mostly see a semi matte version which is a combination of the glossy and the matte masks.

I had the same question. There had to be some sort of advantage to glossy if PCB MFGs offer it. Lets look at interior paint. Glossy paint is a lot more resist to smudging and collecting debris. I assume that glossy solder mask has the same advantage.
