Huge diference between Magic Bullet Looks Looks applied in Final Cut Pro and After Effects

Hi
I'm working in a project where it would be great to get both the editor (working in FCP) and me (AE) synchronize the color-correction parameters of the clips. A work flow where you can switch from one footage to another, no matter the aplication the clip is color-corrected.
The problem is I can't guess what's going on with the diference when applying a specific MB Look in Final Cut and After Effects.
In AE it looks fine but when exported (AE Lossless preset module) and imported to FInal Cut it looks very different.
There is no other plugins or filters applied to it. Just the same customized MBlooks.

The Final Cut sequence settings is
XDCAM EX 1080p25 VBR

thanks!
