In the results reported in the document, does the reference codec have deblocking enabled? Maybe this was addressed before. But I cannot seem to locate it.

But some of > the details might get lost (e.g. the last steps leading to the chapel). It isn't really a matter of stronger vs weaker filter. The encoder can turn the deringing filter on/off for every superblock, so any issue would come down to how the encoder made the decision to keep the filtered superblock. For example, the distortion function could be missing something, or the encoder could be deciding to "sacrifice" some region of the superblock to make another region better.
