Hmmm... two class 767 is nothing special in terms of seating. It's a domestic F product through and through. No leg rests, but bigger seats. However, there are a lot of people up there (34 when full), so the service is affected.
I have not done that route in a while, so the meal service history is probably irrelevant. There will be a meal, though, and it should be decent. (I remember a really good Chef's Salad one time... but I was famished.)
Audio is the same as every other aircraft. It will have an old-school projector in the F cabin.
It may have Empower in the seats (all 767 F seats should), so long as things are operable.
It's not a bad ride.. nicer than the 757 (imho). Just strange how small the E+ section is on these planes.
