They could have made an incremental move in that direction, though. And incremental moves could build up to something more over multiple generations of the Apple Watch. I expected they'd be coming out with a more efficient SoC for the new Watch, and they did in the S6. But they chose to use the extra efficiency to divert more power to a brighter display instead of provide more battery life.
