But you lose the ability to turn on 24hz judder free playback
True -- but if the cinema option is a concern, you can just take the TV out of PC input, and select any other input mode. The calibration and or changes you apply in both ISF modes will yield the same picture in SDR content regardless of input mode. Also my response was more about gaming on the 2017 OLEDS, no reason to use game mode to game or use that mode to experience 24hz judder free playback...
