1. A display device comprising:
a display configured to present image content;
a memory storing instructions and operating parameters for the display device, the operating parameters including a color parameter and an additional parameter that controls light emission of an additional device separate from and communicatively coupled with the display device; and
a processor communicatively coupled to the memory and configured to execute the instructions to switch the display device between:
a normal operating mode in which the color parameter is set to cause the display to present the image content in full color and the additional parameter is set to allow the additional device to emit light, and
a scotopic preservation mode in which the color parameter is set to cause the display to present the image content in one particular color and the additional parameter is set to disallow the additional device from emitting light that is not the one particular color.
