Don't worry, no offence taken. This is just a discussion. Well, since in a month time, the golden head would fade then there is much longer to wait. As for white tank treatment, once the fish is left in a dark enviorement, the shine will fade so there is no need to wait for it to get to at least 12". IMO, the pics don't do both fishes justice since to some viewers it looks "washed out".
I have seen XL's breeding facilities. Seen their white tanks treatment fishes too actually. I don't think it's a case of hobbyist here in Asia not daring to complain about white tank treatment fishes. I think it's a case that we get both "treated" & untreated fishes. Complaining isn't going to change much. Buy with your eyes wide open is a good motto so to say the farms are "conning" us isn't exactly accurate. It's a question of enhancement for some. Lots of LFS would readily admit to WT treatment stock, they don't try to hide that fact. Then there are the exceptions...the once in a blue moon fishes that are extrodinary. The cream of the crop so to speak.
