I double-checked the documentation and it is a HC DaMat, but it is 3 years old and the new ones might be different. You could contact Da-Lite to find out.
I was surprised by the sparkles, too. The screen looks smooth when the projector is off and the room lights are on, even from very close. But there is definitely a sparkly texture in and around the slightly "hot" spot when that part of the image is bright. My old homemade blackout cloth screen had no visible texture, but I get better blacks with the HC DaMat. Overall, I prefer the HC DaMat.
