Craig,
If memory serves me correctly, Philips "better quality" PAL colour TV's
in the late 70's to early 80's "inverted" the CRT for us in the Southern
Hemisphere. The TV's were clearly marked as such on the packing box.
For reasons unknown, Japanese-made colour TV's never seemed to have this
problem. Even though I was working professionally with these beasts at
the time in a TV station, I never figured out why Jap TV's seemed immune
to this problem whilst those made by our Dutch friends were not.
OOLLM I guess.

A bit off topic, but likely interesting to time-nuts:

So, we had a HDTV monitor that doubled as a earth hemisphere detector,
using magnetic flux differential. Needless to say, we only used it in
northern hemisphere shows after that.
