Well I could imagine that the paint could definitely help fend against hood-glare for the driver. I would imagine that it may disperse heat evenly across the exposed surfaces as well, which may keep you from getting any random aerodynamic pressure "bumps." I've always wondered if the presence or lack of a flatcoat would effect the car'* radar/lasergun speed clockability (as it could potentially be less readily reflective to these things).
The sharkskin idea may not be too far off. From the one picture we have, it looks matte black, though it'* not likely (as they'd have to be almost hair-like) that could be due to hundreds of thousands of grooves or "rows" which have been laden into the paint job. Or maybe this is what the di-lithium crystal panelcoating would turn out to look like :P
