That's the older Triton color technology, not ACeP. ACeP has more than 4096 colors and is much more expensive IIRC.

For smaller displays, such as the Onyx BOOX Poke Color (7.8"), the price premium is relatively slight over the B&W equivalent: $400 vs. $350 per the manfuacturer. https://onyxboox.com/boox_nova3color https://onyxboox.com/boox_nova3color https://onyxboox.com/boox_novaair https://onyxboox.com/boox_novaair Yes, the colour experiene is muted. This review seems to capture the capabilities and limits well: https://youtube.com/watch?v=aSUcnkQCa-s https://youtube.com/watch?v=aSUcnkQCa-s Keep in mind that for virtually all e-ink devices, the display properties themselves are dictated by the display vendor, Eink.com, who have a monopoly under patent. It's as if, say, all OELD / LCD displays were manufactured by a single company. (There's a high concentration within that field, but not a complete monopoly.) https://www.eink.com/ https://www.eink.com/ Display characteristics, properties, sizes, and price are pretty much determined by Eink.

Your post is more correct than mine was: the product description says «SB1452-QAA ... with color filter design». But it is more probable that that display is kaleido, not triton (similar idea but upgraded results). Kaleido is the technology used in the colour E-ink displays shipped in the past few years. Also the information I found to refresh my memory was incorrect: yes, 4096 is for the filter. Kaleido uses RGB trichromy. Some information state 32000 colours for ACeP - probably rounding for 2^15. Which I cannot translate into a good guess, not having found more precise information: 5-bit state per pigment trichromy makes little sense, but also 4-4-4-3 (CMYK) is not convincing, or 3-3-3-3-3-3 (?), or 3-2-2-2-2-2 (KCMYOG). One of the relevant matters is that the difficulty for E-ink was to find a method to change the state of the single pigment in the same cell - it is not clear how many pigments per cell they can now control.
