The difference is colour rendering and the nature of the spectrum. An incandescent bulb is, by definition, emitting black body radiation - it’s a nice curve encompassing a good chunk of the spectrum, but as you say biased towards the red end. LEDs tend to emit discrete quantised frequencies of light, as a result both of the dopants in the LEDs and the phosphors used on bulbs. They have got better, due to better phosphors, but they still don’t render colour as well as incandescent bulbs. That said, I’m all LED here as I cannot afford within our energy budget to burn a kilowatt or more on lighting.
