Okay here is my original comparison between the factory CS headliner and SMS:
I think the black fabric is identical but the dark color obscures the difference in the perforations. Splitting hairs here.

The original perforation appears to be molded, not cut. Either that or cut with heat to maintain the shape. They are not holes, they are pyramids with visible texture and clear walls.
