Interesting, thanks for the clarification. The only 787 I have flown on is Norwegian's, the seats they use are very comfortable and show very little difference in width to a BA/VS 747. However where you do notice a squeeze is in how close to the walls and each other they are placed with the edges of the backrests almost touching, whereas on the jumbos there is usually a good inch or two's gap between them. It also had very narrow armrests, although I cannot remember if they went up fully or not.
