I’m not sure what you mean by “all of them”. Are you saying that incandescent light is whiter than LED light? I’m pretty sure that’s not the case.

LEDs use phosphors (usually a few different ones) targeting specific wavelengths, giving it a "spikier" spectrum. https://www.researchgate.net/figure/Emission-spectra-of-different-light-sources-a-incandescent-tungsten-light-bulb-b_fig1_312320039 https://www.researchgate.net/figure/Emission-spectra-of-diff...
