Makes me wonder how much more advanced black and white screens need to get.

No, Pearl with no front light or touch layers with good ambient light isn't much worse than Carta or Carta 1200. My 6″ 167 dpi K3 or 5″ PRS-350 isn't that bad. Far better than the earlier screens.
The changes in 300 dpi screens in last 10 years are marginal. Very slowly the DPI is increasing to 300 dpi or toward 300 dpi on bigger screens.
It looks like there are only minor tweeks over the last 11 years. Kaleido is nearly 4 years old and conceptually older than 2005 eink, it's just a tweak to the printed on top colour filter array (CFA). Triton was simply the standard LCD colour overlay.
The ACeP is something different, but for signage/adverts. About 10 times slower than eink.
Full 14 greys, black and white quality refresh has hardly improved in speed since Regal on Carta 10 years ago. The faster modes are poorer quality and higher power consumption.
Pearl and Carta were the two big upgrades from visiplex.a
