Our controller supports per-pixel update mode settings, but this would need support from the software side.” That “per-pixel update mode settings” sounds very useful for things like interactive books, where the static text could be anti-aliased with grayscale, and moving pictures (physics animation, mathematical graphs, etc.) would be 1-bit monochrome and react smoothly to adjustments. They show something in this direction in their second video, embedded further down in the linked page, where letters being typed are first rendered immediately in 1-bit mode, then after a delay smoothed out.
