Comment (by troy_s):
The rounding is the issue, and I can assure you that all of the values per
channel were encoded 1:1.
The reason a gamma of 1.0 was assigned is likely due to that being
required to prevent the PNG color mangling.
I could provide raw files, but that is vastly less easy to diagnose.
