Quite a bit of what I'm saying comes from working in TV production -

Grade 1 picture monitors continued with delta gun tubes long after PIL
were introduced domestically -- and stuck with the original NTSC
phosphors. As this was the standard the cameras were 'calibrated' to.

But there was no "original" NTSC red phosphor -- just a standard for it,
that the original red phosphors didn't meet.

The phosphors as used when colour TV arrived in the UK were known as NTSC
standard by the BBC. And were still specified for Grade 1 monitors for
many years afterwards. Indeed probably still are.
