Depends on the engine variant.
As I recall a study was done into Perth about 5 years ago. This study was to ascertain why QF 767's had a flatter descent gradient and had trouble in speed reduction.
As it turned out there was in fact a difference within the QF fleet. The GE powered, by memory, had a higher ground idle thrust. Until flap was deployed the gradient was very flat.
The PW had slower flap limit speeds so close to the final approach slowing could be a problem.
If other model 767's had the same flap limits as the GE powered 767, with a lower ground idle thrust, the aircraft would be a lot more flexible.
This is by memory as I haven't been on the 767 for a while.
