The bulb itself was not being ever being looked at. Same for the more modern edge-lit led 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.

The light is never directed backwards onto a white surface and reflected by it, but always forwards directly through the color filters - so at 2 you are looking into the light source.
Without this, you see nothing - neither during the day nor at night.
With EInk, ambient light is advantageous, but I don't need any internal lighting, neither during the day nor at night.
When you look at a backlit surface, you always look into the light source
