I’m assuming Amazon’s “Colorsoft” E Ink display is a form of Kaleido 3 with some Amazon magic sauce around refresh rate. super curious to check out it out compared to the Kobo Libra color which is theoretically using similar tech. I was a huge fan of the Libra Colour’s display, even if it’s hella faded versus LED. Notably the Kindle has more saturated color than the Libra but that could just be marketing. https://www.theverge.com/2024/7/4/24158251/kobo-libra-clara-colour-e-reader-review
