One answer is to stack 3 LEDs on the die, each tuned to the center wavelength of human photo-receptors. Existing RGB LEDs emulating "white" suffer from shadowing effects where shadows have a color based on the parallax between the red, green, and blue elements in the light bulb. This is no longer an issue if you co-locate the emitters.

This works for direct illumination (eg an LCD screen) but fails for reflected light (eg a light).

Technology Connections is the bomb. I think I've watched all of his videos at this point, highly recommend his channel.
