I have two real CRTs (a 4" JVC radio TV and a 27" Sylvania), and while none of the existing shaders perfectly capture it, a guy who calls himself “Retro Crisis” on YouTube and Github has some modified CRT shaders that come really, really close.
My only gripe is that he has different shaders per system, rather than a single “this is your CRT so all games will correctly render through this one” shader.
