Oh, but there was. The original delta gun shadow mask tubes used the
correct NTSC phosphors. Which gave a pretty pure red. The rot really came
in with PIL tubes which used a very 'orange' red phosphor simply because
it allowed a brighter picture. And that had real implications to flesh
tones. Took many years before that was corrected.
