I was working on a PBS Project and upon export I noticed an interesting phenomenon. I had to export a ProRes HQ, a MFX, and a mp4. I noticed that the MFX had a slightly better color replication then the other 2. Any reason that may be?

How are you watching the exported files? There's a widely-known issue with QuickTime Player, where levels are not displayed properly. Using another player (try VLC) will show you a more accurate representation of the levels.
