The 767-400 is its own category. They only fly that airframe, not the 757 or 767-300.
The 767/757 category flies all the different types of the 757 and 767 EXCEPT the 767-400, due to the different panel, ie. Flat screen vs round dials.
There was a time 20 years ago when Delta tried to lump in the 767-400 with the 777 but the FAA said no.
