1. A light emitting diode (LED) display system comprising:
a display comprising a plurality of pixels, each pixel comprising a set of LEDs, each set of LEDs comprising at least a first LED configured to emit light of a first wavelength, a second LED configured to emit light of a second wavelength, a third LED configured to emit light of a third wavelength, and a fourth LED configured to emit light having a fourth wavelength between the first wavelength and the second wavelength;
a user interface configured to receive a user data input; and
a hardware processor configured to, based on instructions stored in a memory and the user data input from the user interface, control the display to provide, for each pixel, a light output from the fourth LED that compensates for a lower external quantum efficiency (EQE) of the first LED compared to an EQE of the second LED and the third LED.
