True white LEDs can be expensive, often cheaper to have rgb trios to emulate white, plus now you can have end user customization. Google “why are the streetlights purple in Florida” for a funny example of this
Interesting enough, the reason LED streetlights turn purple is because they’re actually blue LED with a yellow phosphorus coating that glows white when struck with blue light, and that coating breaks down with time and heat. Especially if it was applied in a particularly cheap manor.

White LEDs also can age poorly, making their color shift sometimes quite significantly.
