Sorry to burst your bubble but a Kaleido screen is simply a coloured filter layer in front of a Carta display. If you pull the CFA layer out of the sandwich in the attached image, you have a B&W Carta display.

The real next generation of display is eInk's Gallery/ACeP screens. These have 4 different colours of particle in a microcup and by positioning the particles, you can generate more colours than Kaleido 3 is capable of and without reducing the display resolution. The problem is that positioning those particles is a slow process. It can take up to 1.5 seconds to rewrite a colour page in quality mode.

For the construction of the ACeP display, see this image from eInk's site:
ACeP microcup since the animated GIF gets converted to a jpg when I try using it as an attached image.
