Depends how you define high refresh rate. By regular e-paper standards the tech it has come quite far but still below the 60Hz you get in any cheapo LCD tech.

Also, the faster you refresh a e-paper display, the power consumption can even surpass power efficient LCD tech so it's just not viable in that case unless the panel has the capability of partial refresh but even then it's not ideal for consuming fast moving content.

E-paper displays are power efficient for static images (books, price tags, advertising, notifications, etc) but if you have to refresh them fully several times a second, the power consumption goes through the roof (moving the e-ink particles around in their pixel compartments requires more effort than rotating LCD crystals/OLED).
