Willing to be proven wrong, of course.
The factory fluid reservoir cap on my car had the green CHF11S sticker. It was partially peeling off so I removed it.

That is correct, some cars are ATF others are CHF11S. It does partially depend on options, production date, and apparently there is some random luck to which cars have ATF vs. CHF.
