Likely less nasty than 3:2 pull down comb effect on movement transferring film to NTSC. Which is why Progressive and Component was important on USA DVD players, but irrelevant on PAL, which usually simply played the 24 at 25.
I hate getting VHS or DVDs and discovering they are badly frame rate converted from NTSC with the artefacts instead of being a Film to PAL transfer.
Even without 3:2 pull down comb effect on movement, some NTSC to PAL conversions (say video camera originated) have disturbing shimmer on panning.
DLP does often use a colour wheel. Only expensive DLP uses three displays and combiner.
I'm tempted to try a colour wheel on a mono camera and the 2" or 6" TV (all three are mono 625). Somehow I ended up with a USA portable 6" mono TV. There is no video baseband in so it can only be fed with US RF modulator! I bodged a modulator and it does display 625 but with wrong height (naturally).
