It's cosmetic. If you roll it out, the paint in that area would probably be worse looking than the dent, and it still won't be completely gone. If you were planning on repainting or powder coating it I'd roll it out then fill it with something like JB Weld, which I've done seveal times. An exception would be if you've got a near perfect match in touch up paint. Semi-gloss black works well for that. Metallic paints are notoriously hard to mach, which is what the OP has.
Ride it, looks small enough not to affect the geometry.
