Here's an inverse solution - when detecting in a wavelength range where LEDs are the go-to light sources and consequently narrow-band, multispectral sensing is easier to do, and the spectral resolution is more sharply defined.

This goes both ways though, as a set of LED dies needs to be available for both photodiode-mode and emitting diodes.
