Yes, but in order to read the small print on a planisphere you also need to illuminate it somehow. It is just a matter of keeping the level of illumination to the bare minimum and there is no difference between a physical planisphere and a virtual one. All the relevant apps have some form of "night mode" which uses either red colour only or a very low level of dimming.
