I would indeed appreciate you reading the whole thing... I did write it to be read, and while it's long, I promise I don't blather on pointlessly. At least by my standards.
But I agree with you. I think we absolutely can make multi-emitter LED bulbs that reproduce the spectrum of incandescent bulbs, being low in the blue, etc. I know people who have looked into exactly that sort of thing, have researched relevant LEDs, good dimmers, etc. They run into the problem that to do something like that, you're looking at a BOM north of $100 (implying a far higher retail price), which is rather at odds with "anyone actually buying the thing."
So I have to ask, "Why are you sure?" I've explained how our current white LEDs work (blue pumped is the most efficient, violet pumped is somewhat better but less efficient), and the work involved in blue and white LEDs literally led to a Nobel Prize (https://www.nobelprize.org/prizes/physics/2014/press-release...).
Physics doesn't have to grant us what we want, and if your goal is "cheap white LEDs that reproduce incandescent spectrums," nobody, so far, has come up with such a thing.
