That may be a different story because PAL TV sets never had them. NTSC
sets needed them because the phase of the color carrier wandered and
often shifted to the green, while PAL sets reset the phase each line and
therefore were always "correct".

NTSC does not, and never had, an inherent problem with phase stability.

I cant conclude anything, but I know 2 things:
1. NTSC is widely known as Never The Same Color twice

Only by idiots.

2. The PAL system includes measures to counter phase shift causing
colour issues, so I can only conclude that the system engineers
thought this was a problem with NTSC.

And fwiw, IIUC PAL rendered colours are designed to alternate the
error line after line rather than get each line colour correct, so
like many such measures it usually solves the problem, but not always.

I have yet to be impressed by an LCD/PLASMA TV. Every single one of them
I have seen is oversaturated and too bright.

isnt that just an adjustment thing? And yes, I agree many wont go dim
enough, but some do.
