I don't like it and it makes no sense at all,

because screens not just not emit natural light,

they emit far too much blue light, too,

which means that everyone should be using some sort of filter (like windows' night-light),

or blue-filtering glasses,

causing the colours to be off.

Perceptual optimization makes no sense, when you optimize for something that's harmfull to the eyes.
