Had JA738J on JL44 (LHR-HND) yesterday (11. Sep). As infrequent traveller I'm not sure if i would have noticed the difference in the first cabin. Only the dark color inside the toilet was an unusual choice that I immedialy noticed. Considering it's been only around for a month the amount of scratched/blemishes on the surface was a bit of a surprise to me (plus what seems like a blue ballpen gone wild).
