It performed better than the Blackmagic codec, but still did not return an identical file.

i had similar problems the other day. I imported a .yuv file with a avid mediacomposer. It had some areas of "super black" (y=13). I thought avid would import raw yuy2 data, but it looks like that the .yuv-import filter makes a conversion to RGB first. Because these areas were always clipped (i checked all import setings). maybe it is also a quicktime related problem. Who knows....
regards and thanks again for this cool filter,
