There's definitely a compression mark (light line) perpendicular to what appear to be dark striations of some sort. It doesn't take much for pressurized liquids or gases to find their way past imperfectly mated surfaces.
*Better yet, I think something happened during the manufacture of the gasket, perhaps when a die stamper was creating the voids. (The light line has a bit of a curve to it, somewhat matching the adjacent hole.)
