That is strange - did you make those files by hex edit or through the Canon Picture Style Editor software?
I saved a basic file with no adjustments from Canon Picture Style Editor and made my changes in a hex-editor. It's very strange that my pf3-file works in the 5Ds, but not in the 7D Mark I / 5D Mark III.

I haven't dug all the way in but from what I've seen it's just down to the existence of many more tags available in the pf3 format. For instance, in PSE, the extra Sharpness settings, Tone curve (RGB), and the entire Six-color axes tab are not saved in pf2 format. I believe the minimum size for pf3 comes in around 450kb. For instance, I saved a custom pf3 out of PSE with default settings, and the resulting file had 3D LUTs inside for both sRGB and AdobeRGB that each took up 216kb of data.
Ok, that makes sense, that the pf3-files are much larger than the pf2-files if there are 3d-luts. Do you have more information about the 3d-luts? Do you know the offsets of the two tables and any idea how to use these informations? This would be real cool if we can have customized 3D LUTs out of Photoshop for example. We could nearly reproduce any effect/filter made in Photoshop.
Just a guess: maybe Canon PSE creates a 3D-LUT in the case of the PF3-format out of the seetings made with the Canon Tool and uses this one to make the adjustments in the camera. This would be an explanation why my changes in the PF3-files are ignored in the 7D I and 5D Mark III.
