First, the OP lists their location as "earth". So it is not clear WHAT market they are in. Different markets offer different options. Some markets get specific seat options...and some can get all of the seat options.
So the best suggestion I've read so far...which should remove ANY doubt as to how the car is optioned is to use a VIN decoder. Except the VIN decoders require the LAST 7 DIGITS of the VIN (not the last 6).
These are my 3 favorite VIN decoding sites...the mdecoder site is usually the easiest because it normally doesn't require answering a CAPTCHA puzzle or question:

For example...I've never seen the actual F06/f12/f13 "sport seats" offered in the US market. They have headrests that look exactly like the rear seats...and they also have the thigh extension feature...but are offered in Dakota as well as Nappa leather (and some markets even have versions that have a combination of Nappa leather and Alcantara):
