Question about GPU RGB

I read that due to to fact that most GPUs don’t have certain things that are required for RBGIC lighting. Basically, it is limited to one zone due to the fact that GPUs don’t have the ability to store effects like other components do and cone only be a single zone. The only thing is, using Mystic Light, I can have RGBIC effects (chasing effects) on the GPU. Granted, it is limited to an extent on what it can do.

So, I am curious, why can I do it with Mystic Light and not SignalRGB?

One more question, is it something currently in development or is it even possible?

(I have a MSI RTX 3060 and below is a link to the post I found this information from)
