I'm not sure if this is an error on the GNOME side or on the Brother

AirPrint is not exactly known for offering a lot of options, it is mostly
Apple-style "print this thing for me", take it or leave it.
That said, the screenshots on Apple's own AirPrint page do show some basic
options, e.g., enabling or disabling duplex mode on printers with a builtin
What you will definitely not get in AirPrint mode is options such as
printing using CMY instead of CMYK if you are out of black ink (though some
printers do not even support that at the protocol level, because they take
only RGB input and convert that to CMYK the way they fancy). (But does the
proprietary driver even allow you to do that?)
So it is hard to tell whether the lack of options is a bug somewhere or
whether it is just the printer exposing by design only the bare minimum
interface to tick the AirPrint checkbox in some checklist.
I must say I have never tried AirPrint mode because I have only used
printers with working Free drivers so far (HP printers supported by HPLIP
without plugin, and now a Canon multi-function printer supported by
Gutenprint and SANE).
