If it alters the colors it has to be a reencode by definition. The question is whether it’s a reencode of an already reencoded version, or whether it’s a reencode of the master file (so, how many generations of encoding has it undergone).
Yeah, I think it’s a reencode of v1.0, not the master files, but I just wanted to check here to make sure. I was having trouble finding the official v1.4 but found the regraded version quite easily.
