Thanks so much for your responses. I know the barrier prevents passing between the two middle seats. I've flown several times in J on the 77W, and this looks similar but with less privacy in the middle (which may play in my favor this trip). I was hoping it would feel more cozy and private to me and my service dog being in the bulkhead with nobody in front of us, and with the lack of divider between the two middle seats we would feel enclosed altogether, but I wonder if it will be less private? Also, if the galley noise is so extreme it may worry my service dog. Is it that bad? Light seems a nonissue in this short day flight.
