NTSC versus PAL
In the UK, colour was only transmitted on a new 625-line
service (newish, in the case of BBC2), in parallel for a long
time with a monochrome 405 line service (except BBC2),
and I'd have thought the new transmission infrastructure
could have been built to obviate the non-linear group-delay,
given that it existed in the USA.
You're probably correct.
