IIRC that's not the e-ink screen itself refreshing faster, it's a different display driver (hardware! not a driver like radeonsi) configuration. Having the extra chip is expensive, which is a cardinal sin in a loss-leader device that basically everyone just looks for the cheapest model of anyway.
Unless you mean stylus-drawing is higher refresh, which is completely different tech as it's driven by the stylus and can't refresh that fast without the stylus at that specific point.
Anyone seriously claiming e-ink screens can hit 24FPS (the whole screen, not refreshing individual pixels separately for an interlaced illusion of higher framerate) is simply ignorant. You're talking about a whole order of magnitude difference, when the core problem is a straightforward fight against physics.
