all true but 'white' LEDs still look blue, not white.

Depends on the circumstances. They will look white in
midday sunshine. They will look blue when the ambient
lighting is lower colour temperature and dimmer, like
sunrise or sunset, or artificial lighting indoors.

Then there are 'warm white' LEDs, which actually exhibit a tungsten-like
spectrum, without much obvious blue peak at all.
Not quite as efficient as the cool blue ones.
