It's excessive blue that's usually a problem on any solid state illumination, not red. Most LCD are as problematic as OLED because OLED are not "real" LEDs like used in indicators and large hall displays, they use phosphors that are less good than CRT phosphors, but better than the dye filters on LED panels. Really old LED panels use phosphor coated (on inside) CCFL tubes (even 1st Nokia Communicators and Monitors/TVs for many years later), but current LCDs use blue/violet LED backlights with yellow phosphor for white lighting. Only very expensive LCD panels use R G B LEDs.
The front lights on eInk are either blue/violet LED with yellow phosphor or a mixture with some being orange LEDs. They at at the edge.

The yellow phosphors age and give less light, so the "white" gradually takes on a purplely/violet/blue hue. Except OLED may ALSO have blue phosphors which age faster!

Any overlay will make the capacitive touch less sensitive, make resistive touch much less sensitive and may stop IR touch working, depending on screen design.

Use volume buttons as page turn on a Tablet/Phone and have a larger (7" to 8") eink with page turn buttons. Setting font size and line space setting a bit larger helps if you are doing a lot of highlighting or annotation.
