You're actually asking the wrong question. "Why is there such a thing as directcolor" would be a better question. After all, if there's no "speed benefit" when why do manufacturers bother implementing it?
Could it be because it allows colours to be dynamically allocated? Given a "good enough" allocator which looks over your complete colour usage, you could probably make better use of the available colours than truecolor allows.
