Windows Phone 8 and 8.1 had the option to adjust the color temperature and saturation of the display in the display settings, as explained in this article. When I updated my old 8.1 device to Windows 10, it retained this option. However, on my new phone with Windows 10 installed by default, there doesn't seem to be an option for this.
I searched the app store for a f.lux-like app, but sadly there are no apps which can do this. I hoped that SysApp Pusher might let me download the old display settings app, but that also failed.
How can you adjust the color temperature and saturation in Windows 10 Mobile?
