Yes, reflectivity should definately go down, and now that I have been looking at our brick database, and why we have the bevels on our bricks - here is why:
When you build with lego in the real world, the tiny torque in the plastic when you put them together, will make you able to see the gaps between the bricks. On the computer, however, that distortion or torque dont apply, so the gaps would be gone - and that is why we have the little bevel even on the sharp edges - so we can see each brick.
