Effects and transitions ... ahh. Those can be different in every app, and are the bane of colorists worldwide.
What effects and transitions? Some transitions are easily ignored by the colorist, as when their work is applied back in the NLE, the transitions are simply applied to the replacement media. The full "round trip" process.
Some ... are a pain, as the same effect does not happen in other apps. This is the sort of thing to talk over with the colorist. Sometimes they need the original media with the XML/EDL and some budgeted time for the conform process. They pretty much always need a flattened file export to use to check all clip lengths and effects, speed-ramps, frame resizes and that sort of thing.
And some projects ... it's better to send a file to them in a full-digital-intermediate format so they can cut that up and grade that file.
And "scale to framesize" in Premiere is almost always a no-go in Resolve. Set-to framesize is preferable.
