Steering fluid; reservoir 'ATF' vs dealer 'CHF' ?!

Z4MC built 2006, documentation states 2007.

Reservoir states ATF, but the dealer's system prescribes CHF hydraulic fluid based on vin LK 43835 :(

I tend to go with ATF, doubting that the reservoir was ever replaced with a faulty one.

Another suggestion could be dipping some cloth in it and checking the color, I understood that ATF is always supposed to be red and hydraulic fluid another color.

What would you do ? 8)
