KLM Flying Dutchman - seating question

So i got a reservation to Dar-es-salaam in December.

YYZ-AMS: seat 23A (Boeing 747)
AMS-DAR: seat 15A OR 17A (Boeing 777)

would anyone know is 15A has a misaligned window?

forgot to add, does anyone know if the flight AMS-DAR in december is a boeing 777-200ER OR 777-300ER

reason i am asking is because i noticed on seat guru they have different seating.

You asked this question in a new thread as well.

Go to Manage My Booking on the KLM website and you will see the seatmap for your flight. On the 772 seating in Y is 3-3-3, on the 77W it is 3-4-3.
