Practical Color Theory for People Who Code (2016)

Any three-primary system is going to cover a triangle of colors. RGB primaries cover a fairly large triangle. If you wanted a larger gamut, you might consider switching to four primaries. You can still encode colors using the RGB space and convert to e.g. RGBY in the display or whatever.

I do note that this is a limitation mostly for physical systems/models. For non-physical color spaces you can make a triangular shape cover far more of the human visible gamut by having the primaries be "imaginary", i.e. not real visible colors. ACES AP0 is one great example of that

Yes, if you had something like a RGBY display, you would probably use a high-gamut RGB space to encode the data and do a transformation prior to display.
