BMW OEM CF door pillar VS ebay CF door pillar?

Has anyone bought either BMW OEM CF door pillar overlays or aftermarket CF door pillar overlays(ex. ebay)?

My car's rear door pillar got scratched up while it was at the dealership being serviced. (polished outside chrome door mouldings to remove water marks)
I'll need to talk with my service advisor today to see if he will replace door pillars or not, but I know that he won't likely replace it.

So I'm looking at these Carbon Fiber Look door pillar overlays, and I just want to get opinions on quality difference between OEM & aftermarket products.
(Like condition of sharp/smooth edges, CF pattern, how glossy they are, etc..)

And does anyone find it weird that OEM CF door pillar overlays only comes with 6 pieces instead of 10 pieces like it should to cover all pillars? How do they look when installed?
I saw some partial photos on this forum, and it looked somewhat weird. It looked as if someone took them out after you installed them.

Thx in advance.
