It's not clear just from the results whether or not white has a significant advantage. The difference is much greater among lower rated players than among higher so I still think that white is easier rather than "better" in a theoretical sense. When I have some time I'll run through the results of all completed tournaments comparing results by colour, it may transpire that black's results will have improved over time with the aquisition of experience.
