Colour wheel cameras were used on the Apollo moon landings. A 3 tube camera would have been too big and heavy.
3:2 pulldown can be removed from a recording. Sometimes called reverse telecine. I think this was first developed in the late 1980s or early 1990s. It has to recognise the 3:2 cadence, then correct it. If the cadence jumps too often, which can happen if the video is edited after the orignal TK, the problem is a difficult one.
The modern version of colour fringing is failure of de-interlacing. A lot of older LCD TVs had poor quality de-interlacing giving truly horrible effects on moving objects.
