Refresh rate. If all a smart watch did was be a watch, it would be sufficient, but there would be no reason for it to exist. Once you want it to do non-watch things, you need a better refresh rate.

Ok, I don't know all that a watch is expected to do because I don't own one. But AFAIK, messages, fitness tracking, and remote controls do not need anything above what some e-paper can get you.
Now (after some time to think) I do think it's mostly a design restriction. Nobody was able to make an e-paper watch look futuristic and expensive.
I don't know how much research is ongoing into it, and I do think it's underutilized (I can't understand why smart watches use LCDs), but there are many breakthroughs before we can get those things you mention.
I still expect it to get all over the world, eventually.
