That's odd. Why wouldn't I trust internet scans? Internet is vast, it's a huge data set. Large data sets are a valid research tool, that's primarily how drugs are developed. You do not have to be a genius to run a search, look at hundreds of photos from various sources and come to reasonable conclusions. Besides, I've gone through two rolls myself and got the "swampy" look, I asked on photrio and got several swampy samples in comments, seemingly liked by others. Then I've gone through internet data set and 99% of samples had the same swampy look. Then I had experienced people discover post-processing pre-sets that simulate the swampy look. Apparently green/magenta tint is well liked, as evidenced by my wife's reaction.
I have no reason to believe in existence of some "true" Fuji 400H color profile, which the entire internet conspired to hide from me.

A more plausible explanation is that my preference for color deviates from the majority here and I'm OK with that.
