I never did answer this, sorry.
The grain structure visible is definitely in the Clearpix 4k fabric from what I can see. If I find a part of the screen I notice the grain on in eg some bright sky scene, and put the Dreamscreen sample over that part of screen, the grain disappears.
I think I got to the bottom of the apparent softer image on the Dreamscreen when viewed up close.
From what I can see, the slight softness is in the projector image, not resulting from the screen. Because the Dreamscreen has a much tighter weave, you see all the softness.
With the Clearpix 4k, the surface is rough and there are quite a lot of "holes" visible through the weave. This means not all the projected image softness is visible - some of it is replaced by darkness from the lack of weave in the position. This makes it hard to assess the sharpness up close to the screen when comparing.
From seated benefit of the lack of the grain structure in the Dreamscreen is a big advantage IMHO.
