Or D55/D50 rather, in Settings > Devices > Colour The built-in colour profiles aren't accurate in an absolute way but they do let you change things in a relative sense. It seems like the system assumes the default colour temperature is around 6500K, so choosing D65 doesn't change anything (even though your monitor may be well above 8000K in reality). But choosing D50 or D55 will lower the colour temperature to something warmer (redder) like night light does.

Examples: Minecraft Nvidia Settings World of Warcraft via Wine. You can go into settings and manually toggle "Night Light" off and back on in order to get the blue light reduction to take effect again. Not all application/games will cause this. Rocket League, Civilization 5 are examples that do not.
