When comparing the Donkey Kong photos... the color of the Displays "Whites" look too "Blueish". There should be a menu option
to change the displays color profile, to a "Warmer" color tone (more reddish hues). This will make the colors more true to life,
and far less Harsh on the eyes.
That said, some older display tech, had the older LED technology... which were not capable of producing that Warmer tone.
More modern LEDs now have the capability, of reproducing a much warmer White. You might be able to replace cooler-LEDs with
warmer LEDs.
