Apparently to get commercial green or blue LED , GaN is needed. However, the other colors are produced using gallium in combination elements such as Al,As,In, P etc. If my interpretation is correct, the 43% market share for Cree would mean that it's 43% of the green to blue wavelength LED market. Since the other colors have been around a lot longer in LED form, they probably constitute the bulk of today's LED market.
A quote I ran across "the goal of the semiconductor market is to go from indicator technology to illumination technology" With the blue LED that has become a possibility for the first time, though that's a very long way off except for specialized applications. There should be enough of them for Cree to flourish.
