So with a better photo, maybe we could help you more. Looks like strumming marks ... like serious ones below the soundhole. So... the thing is, it's probably through the finish (obviously) and then also there may be a stain on the mahogany as well. If you'd swipe some denatured alcohol over the area.... then you can see what it would look like with clear finish over it. If it doesn't match the rest.... then probably stain or stained lacquer... i'd think some local stain then new lacquer. But does it bother you much? I think it's cool but.... you could fix it. If you want.
