macsforme e-ink seems like it should be ideal for comfort even on macOS
Sometimes e-ink can have other issues that aren't directly related to post-processing
For instance, the way most e-ink devices implement dithering for the "fast" modes — which is used because fast modes physically can't show any shades of gray — is really noisy and chaotic
Because of this, e-ink devices usually show a lot of flicker while scrolling or during animations. This often creates artifacts in areas that aren't moving too, even if the PC's signal has no dithering
In HD/slow modes you also have high-contrast flashing whenever an area refreshes, i think jordan has mentioned before that they were sensitive to this

Another example: although e.g. Boox is better than many screens — E-ink is still not that ideal for me indoors, due to the blurry look caused by layers above the panel. I assume Dasung may have similar issues
Some prior notes about this in the "details" link:
Instead of the output or light being the cause here (the Boox frontlight is off and I've tried using it under different types of lightbulbs such as incandescent) —
It's more that the multiple layers and matte coating Boox places over their makes text appear really fuzzy — unless it's in sunlight for some reason where text becomes sharp
After I use the Boox indoors, I sometimes end up with blurry vision afterwards
Fortunately, It's definitely not the same kind of really disorienting blurry vision that problematic LCDs cause — only lasts for a bit instead of hours.
But, there's definitely something about how the glass/plastic layers on e-ink panels look that doesn't feel natural to me

What's interesting is I have found that for reading indoors, compared to e-ink, I actually often prefer a PC with good output connected to my Sanyo Z2 projector
(The projector uses a halogen projection lamp, and 3LCD which creates the appearance of perfectly square pixels that look like true colors, even up-close, instead of RGB stripes)
I've configured the PC to show pure green, pixelated text with no font smoothing on a pure black background. Basically true monochrome where every pixel is only "on" or "off"
Even though this does rely on illuminated light, it creates text that looks extremely crisp and "natural to read" for me.
I personally find this more "paper-like" than e-ink. As text looks very flat, like it's directly printed on the wall, instead of diffused by a couple of layers
