There are software solutions that exist yes, (DOSBox Staging as mentioned below, certain RetroArch shaders look very good) but neither really represent an actual product — DosBox Staging is supposedly zero config but simultaneously requires configuring a DOS environment. Replicating a shadow mask, or curved screen for example requires fiddling with shaders, not to mention aspect ratio, the size, or display resolution.

In any case, most emulation software is geared towards gaming — many art galleries for example still use CRTs for preservation (https://www.nytimes.com/2023/10/17/t-magazine/technology-art..., https://youtu.be/rHBtmPZx82A?t=1828) and these software solutions don't really fill the gap of a general-purpose CRT display.

DOSBox Staging has the best CRT emulation I've seen. It's subtle, but it really feels like going back to a VGA monitor.
