LCD panels are also inherently monochrome. No-one quotes the mono resolution, because that is effectively "damaged" by the coloured dots or stripes. Only the effective resolution without artefacts is quoted.
If you want no artefacts ever, then it's exactly 150 dpi, like my Kindle DXG, except you can read it in ordinary ambient light, you can't do that with Kaleido. That's the biggest remaining advantage of eink lost.

No, I've admitted that fine mesh screentone in manga can have a visible rainbow pattern. It doesn't effect all manga and how impacted a book will be depends on the artist and their use of fine mesh screentone which can range from never to every page. Some manga also have colored pages that are "ruined" on a B&W reader.
You are never ever going to trigger the rainbow artifacts problem with ordinary black text at any reasonable, readable size. It's just not a problem. So no, you don't need to run it at 150 DPI (and they don't) because you're not going to encounter it outside of special cases in pictures/illustrations. It's essentially moire. Nobody quotes resolutions for ZERO chance of moire.
Normal color LCDs can't produce white without turning on all subpixels. So you can't use the full "mono" resolution.
I read the Libra Colour in ambient light all the time. Even on crummy overcast days.
Unlike you I actually have experience using a Libra Colour and more than a few minutes using a color eInk device. Stop spreading misinformation. Seriously. It's not even REMOTELY like 150 PPI text.
