Hey! I released a shader-based CRT emulation process setup I made in Blender (for both Eevee and Cycles engines).
Check it out at https://mrmotarius.itch.io/mrmocrt !
My main intention was to evoke the actual "feel" of CRT displays.
I implemented some UV manipulation to "fragment" the input image (or video, or procedural texture) to the CRT's shadowmask grille, which results in a nice spatial quantization and no "cut" RGB phosphor trios. It also features a bunch of exposed, easy to tweak parameters.
Here's some sample renders:
