On “Show HN: Rainbow – an attempt to display colour on a B&W monitor”

JVC built a working model with that approach. There's a neat breakdown of the tech on this YT channel: link to this video

On “Why is the red primary color oriented at 104° on a vectorscope?”

Tangential but Alec Watson of Technology Connections looked at a studio monitor that worked on the principle of cycling an LCD overlay over a monochrome CRT. When I was growing up in Toronto, I want to say that I remember seeing these in use by “LiveEye” crews of CityTV whenever I went by an on-location shoot. (1) link to this video

On “Advantages of CRT over LCD”

The Sony Watchman1 had the electron gun at the bottom shooting at a tilted screen instead of shooting at it from the back. This allowed to make a GameBoy-sized portable CRT TV. There is also an interesting LCD/CRT hybrid from JVC2, it's not flat by itself, but the way it adds color to an otherwise black&white screen could be used in slim designs. 1 link 2 link to this video

On “A Tektronix TDS 684B Oscilloscope Uses CCD Analog Memory”

Modern video projectors also display color channels sequentially and also exhibit that effect. Also, this particular CRT technology was not only used in oscilloscopes: link to this video
