I also have a Daylight on order... but isn't the main thing with the Daylight that it's not a true/typical e-ink display, and that's how it gets such a high framerate? My understanding is that it's a first-of-its-kind thing, so "removing color" is more like "we haven't gotten to color yet." Although I hope they eventually do!
It’s using a reflective LCD panel. I’m curious if that panel is limited to b&w or if it’s a typical color LCD limited to b&w in software. Color reflective LCDs exist (I saw a LTT video where they reviewed a desktop monitor using one[0]), they are used in digital signage and less on the consumer side.
Daylight does say they made modifications, but haven’t gone into a ton of detail around what those are (at least not that I’ve seen).
