zip file containing the icc color profiles in question
SUMMARY
I want to apply the ICC profiles that came with windows on laptop, provided by
the manufacturer.
The display itself supports P3.
When I enable the "sRGB" correction profile for my display on Windows, the
colors become more washed out, as one would expect.
When I copy the same icm profile to linux and enable it for kwin, the colors
become more saturated.
Also, the DCI-P3 profile makes the screen darker and more contrasty on windows
(expected outcome) but the effect on kwin is the inverse: the display looks
bleached and missing darks.
Attached are the icm profiles in question.
I have taken photos with the same camera settings (white balance, exposure,
aperture, iso) to show you what sort of a difference I am seeing. I set the
screen brightness to full in each photo. I restarted firefox before each photo
after changing the color profile. Windows automatic color management is
disabled.

Note the color shift from windows profiles to linux
