Not particularly. In terms of empty weight the smallest 787 starts 16 tonnes heavier than the biggest 767.
And most 767s are -300ER which are 27 tonnes lighter than a 787-8 at empty. For an airline that doesn't need the extra range capability of the 787 that's equivalent of a fully-loaded CRJ in extra weight to be lifted. 787s are more efficient on a seat-basis ( and about the same in trip costs ) but against that have to be offset the higher capital costs plus all the hassles of introducing a new type.
So for an airline such as United with an immense 767 infrastructure I can see why adding more new-builds would be attractive.
Incidentally the 787-8 / -9 are pretty much direct matches in floor-space to the A330-200 / -300 respectively which slotted-in just above the 767 series.
