Gamma/color shift on export at DVinfo.net

[This is subsequent to a post in the Cineform forum, but there's some reason to believe it's not a codec-related issue.]

I'm back to seeing something I was experiencing a while back and never got a satisfactory understanding of. Now I'm seeing it again, so I thought I'd ask for some general input in case I'm just completely missing something obvious application-wise. (What I had seen before seemed to be an Adobe-related gamma/color where their version of a clip looked different from every other application.)

Sequences are Cineform 720p/23.98. Color correction is done in After Effects, and exported to CFHD. When I bring the exported sequence back into the same AE project for comparison, there's a color/gamma(?) shift.

Attached are three images for comparison. The first is the original frame from AE. The second is the exported footage brought back into AE. The third is split with the original on the left and the exported on the right. (The split is most obvious on the side of the building.)
