With emulation, there's always a deeper level of emulation you can do to approach "perfectness". In this case, the pinnacle of emulation of a CRT is to simulate photon emission in a tube, and simulate the response curve of each phosphor element. To do that would probably take a supercomputer to effectively calculate real-time. According to this paper, there are (1.12 x 10^16) photons per second produced by a 1-lumen source over the interval from 400 to 700 nm . And with a 200 nit CRT is roughly 600 lumen... which is roughly (6.7 x 10^18) photons per second... if you just model them as a particle.
