The FA-Seats come imho from the front. There the fuselage sleeks down already to the cockpit. The anunciator Panel got separated, if you draw lines from the brown spots (holes from screws broken out) you get the panel-size. The headrests are gone as well as the plastic cover. However the metal fixings of the plastic panel are visible.
Note also the opening to the lower right of the panel besides the seats. In the picture below there is an access panel visible.
I only found a picture (hope the link works) of those seats from a Ethinad-Airways A330, but you can see the point.
