I see KL charge for exit row window seats on the 772 (31A & J) but not on other aircraft.

I was under the impression that all the window seats at exit rows had restricted legroom due to the raft/ slide being housed in the lower section of the door that sticks out into the cabin. Is the 772 different?

Has anyone sat there before? I'm flying AMS-KUL in Jan but thinking of purchasing these seats for the extra leg room.

Thanks in advance.
