I have a thread in the users section about this that has all the details and links to sample files. In summary, montage appears to be shifting the dynamic range of 16bit EXR's when stitching the final output. The thread on the users forum is here:

Re: Montage shifting dynamic range
After more tests, it is clear that montage is shifting the dynamic range *of each channel independently*. If it's going to do it by default, it should at least do so equally to all channels. I still propose it shouldn't shift the dynamic range whatsoever. After all, its primary job is just to join pictures together, not modify their content.
