How does the emission mechanism of a star differ from that of an engineered laboratory light source regarding color saturation?

Answer

Stellar emission is continuous and broad, whereas laboratory sources can emit light extremely narrowly at a single wavelength.

Laboratory sources like LEDs can be engineered for very narrow, saturated colors because they are not governed strictly by thermal radiation across all wavelengths, unlike the continuous, broad emission from superheated stellar plasma.
