As there is a color difference Bridge and Photoshop, could you please have a look at this forum thread and let us know if it helps?Color Management Discrepencies Between Bridge, ACR & Photoshop
To be quite honest, I'd ignore that thread. It chases red herrings for about 50 posts, before fading out into nothing.
First of all, I'd try to right-click the thumbnail and "purge cache for selection". I've noticed that Bridge color management can get stuck, and the file displayed without color management at all. Forcing a preview update clears it, and the colors snap to normal.
If that doesn't do anything, it's a broken monitor profile. More often than not, broken profiles affect applications differently - some handle the profile while others choke on it. Recalibrate, and make sure ColorNavigator is set to make v2 and matrix-based profiles (called "gamma value" in CN). It should not be set to v4 or LUT-based profiles, both of which can sometimes be problematic.
Also worth noting (but not the issue here) is that Bridge previews are sRGB jpegs. On a wide gamut monitor you may see gamut clipping in Bridge vs. Photoshop. On a standard monitor this won't be noticeable.
However, it does explain why, if Bridge color management is stalled, the previews display oversaturated on a wide gamut monitor.
