It won't. I understand what you are saying about not wanting anything to be altered at this stage apart from the color, and that's fine, but you shouldn't apply RFF flags to 29.97fps video. At some stage, you will have to slow it back down to 23.96fps and then encode with RFF flags i.e. apply pulldown.

Sorry if I'm being dense, but what do you mean by "slow it back down"? The frames that are currently in the movie already correspond to 24fps, not 30fps. Why do I need to slow it down further before pulldown? I didn't do that for PG or PSB (at least I don't remember doing that).

By the way, thanks everyone for helping harmy look into this!
