Do you have any insights on what options the online decoder might be using, or how this might differ from your wrapper?
Are you using either AZTEC code or PDF417? I made a couple changes to improve those decoders upstream (see https://github.com/zxing/zxing/commits?author=dlenski), but they aren't yet in a tagged release of ZXing.
Other than that, I don't have any ideas about known deficiencies.
Happy to share data privately.
I'm definitely interested in seeing them. You can email to the address on my profile.

We resolved these issues by aggressively augmenting the images. We create a basket of different versions of the image transformed by intensity and thresholded at different gray levels. This brought us to a 98% read rate. I'm closing this since it seems like the decoding library is working fine.
