With a 4K display and HDR, we can actually do really decent CRT emulation. It seems a bit ridiculous to need 4K/HDR to emulate 40 year old display tech, but you need the resolution to do the aperture grille in a way that's small enough to work, and you need HDR for that phosphor glow.

The Retrotink 4K has been pretty eye opening (and eye-watering, given the $750 price tag) in terms of where we are with CRT emulation these days.
