That's still not consistent with my understanding of the current Open Pro line up. CD and Ceramic are currently listed as completely separate options.
For a bit more than the regular OP rim, you can get a CD finish, which is an anodization process reinforces the oxide layer forming a greater micro-hardness to reduce wear and corrosion.
For a good deal more than that, you get an actual ceramic layer added to the braking surface to improve friction.
