There is an important factor that is almost always ignored in the discussion: the screen/monitor size. I use a LG 27" Monitor on my working place and the amount of light that is emitted in light mode is literally blinding (as in snow-blind). Turning down brightness enough to become bearable badly affects contrast and chromaticity. That is the good thing on dark mode: that colorful content remains unaffected. For me it is dark mode on large screens and light mode on phones and tablets.
