Flew on 787-10 on BA192 a few days ago in CW. One "caution" is that 6A/K window seats have one set of windows only, across the seat. The second further window adjacent to the screen/display that all other seats have is missing - this might be an issue for some people but I preferred it as there was likely less glare on the screen. The issue is that if you like to look out then you almost need to turn your head 90 degrees vs a slant 30-45 to look across the other window.
Also the privacy doors, while a nice touch, after a while seem gimmicky and most of the cabin didn't bother with them at all.
