Have you tried blue-block type lenses? Not those yellow ones from infomercial - it's a clear lens that cuts some wavelength for staring at bright monitor all day. Lots of cheap readers have those.
This was not my point. My point is that Apple uses old panels, which are pushier on eyes, instead of asking LG to put normal backlight. A supposedly premium manafacturer stuck with the panel from 2016; Apple stopped innovating, outside the M cpu series.
Btw the lenses still are yellowish, and interfere with white balance. Attempt to correct the white balance will destroy the effect of the lenses at 450 nm will be back.
