I believe you are right, but not exactly the easiest angle to ID from. The bill coloration on the adult birds are hard to see and can't see if there are any wing bands from this angle. If you have pictures from other angles it would help.
I would guess that the bug actually is on the way up, as it is in the mouth of the adult bird, who is about to feed the juvie.
Great picture, by the way.
