I have a work flight coming up from Vancouver to Sydney and have been booked in premium economy. My assigned seat is 14H. According to seatguru this "may" have limited recline due to the bulkhead wall directly behind. Does anyone with knowledge of this aircraft know exactly how limited ? Or will I be stuck in a full upright seat for 15 hours ? ( also, for some reason the AC app says " set selection not available for this flight.... perhaps because the travel date is sill a month away )

interestingly, I am booked on the same seat for the return trip, but this time the aircraft is a 787-8
