Hey, OP, I just did this flight last week. IIRC, the flight (then) dep ATL at 11:19AM and was scheduled to arr at 4:30PM the next day but we hauled it over the North Pole so we got in about 50 mins earlier then scheduled at about 3:40PM local time. Total flight time was 13:51 and meals were dinner, mid flight snack and I have to admit, I don't remember whether the third meal was breakfast or lunch. I THINK it was lunch b/c on the return flight on KE we arr in JFK at 7:30PM and were served breakfast before arrival and I don't remember that same meal service on DL before landing in ICN so I think it was lunch.
