I have Jerez on Bamboo and love it. From my experience, BMW's black leather does not hold up well over time. Cracks and wear are much more obvious on the darker colors. You can always clean the lighter colored leather. I have had my car for a little over two years and the bolsters have held up fine.
Check here for pictures of all the factory colors.
