Patrick,
Can you elaborate on what process you're using Final Cut Pro/Motion? Is this from within a plugin, or are you comparing the built-in blend modes with QC? (In other words, are you creating a project and using the functionality of the app without any plugins?)
The first thing that comes to mind is that they may be operating in different color spaces which would cause the color values to be displayed differently. But that's just a guess.
