Description

When interacting with the night mode feature, I found an inconsistency where the set temperature is not followed when toggling night mode on/off. When you go to enable night mode in the settings under displays and configure the color temperatures for both night and day, the screen will update to the appropriate gamma. However upon toggling the night mode switch on and off (this applies as well within the control panel, not just settings) the color temperature seems to ignore the configured values in the settings and defaults to the regular night mode gamma.

Expected Behavior

Configuring the gamma control section and toggling night mode on/off should correctly apply the right color temperature.

Steps to Reproduce

1. Enable night mode
2. Set night temperature to any value (e.g. 3000k)
3. Do the same for day temperature (e.g. 6000k)
4. Now disable and enable night mode and the color temperature will change to a different value
