With an illuminated EInk, the light is cast from the front onto the module and you see as you see everything normally - reflected.
And it is a difference whether you look into the light source or look at something illuminated (not mirrored).

I think you might be oversimplifying just a bit. I've disassembled quite a few LCD devices in my day, and most didn't have lights directly behind the viewing portion of the screen. Especially with some of the smaller screens. The old-style fluorescent tubes were typically at the bottom and/or top of laptop screens and were shined up and/or down. The bulb itself was not ever being looked at. Same for the more modern edge-lit led lcd screens.
I'm not arguing that the different technologies don't affect different people differently, but clinging to the notion that people are looking
directly at the light source with lcd devices is neither accurate, nor helpful. Yes, the screen on an lcd device is glowing; from lights that are located behind (or at the edges of) the screen. But people aren't looking directly at the source of that glow. Just like people aren't looking directly at the sources of light that make an Eink screen more visible.
They're different, for sure. Just not "
staring at a lightbulb" vs "
staring at what a lightbulb is illuminating" different.
