More like "fundamentally impossible". Even ignoring the limited colorspaces due to choices of primary (i.e. the fact that no laser's color can be emitted by a screen), and assuming you calibrate your "white" (most screens are overbright these days), it turns out the pigments are really bad at "reflect exactly this pure-ish wavelength and absorb everything else", which is very frequently done by emitters.
Perhaps OP is offering a first approximation and not attempting an impossible platonic ideal?
