Does the 777-9 have the 787 windows? That is, the ones that don't actually block all the light and little of the heat when set to dark, don't allow you to close off the upper part of the window while looking out of the lower part, typically are set to be controlled in groups in business class instead of allowing individual control, and let authoritarian crews set them to dark even during daylight flights?
Or do they have useful, passenger-oriented windows?
