I think my conclusion that different colour models work for different purposes (art, electronic display, and printing) is a fair one! And yes, I was conscious of asking what you 'think of' as primary colours; that is why I followed up with a discussion and opinion.

Your comment about RYB primary colours not being created by mixing other colours is blatantly false - red can be made by mixing yellow and magenta ink or paint, and blue by mixing cyan and magenta. And if fine arts is teaching RYB as a basic colour model that must be very limiting, as many artists used a wider palette.
