  Merit as a musician can only take you so far. In any creative career, the big famous artists aren’t just good at doing their craft, they’re also very good at making business deals to sell them. And even that’s not always enough to become a superstar, you also need luck - your breakout/masterpiece needs to coincide with the latest trend, and preferably early in your career - a one-hit-wonder might be enough, but maybe not.

  LCDs are designed to filter out extremely specific types of light, and in a specific direction.

  It’s true that the changing optical properties of each crystal could affect the albedo, but whether white or black is more effective is beyond my knowledge. It might even be neither, but green instead.

  No, and not because the effect is in any way small.

  It is because a phone screen producing white light, looks white because it is actively generating white looking light. Compared to white paint, which looks white not because it generates its own light, but reflects other light, these are two different mechanisms for making things look ‘white’.

  Your phone has a brightness setting, to keep ‘white’ the exact same shade of white despite whatever viewing condition you have. A white paint does not, and as a result, looks different depending on the amount of light in the room.

  So in your hypothetical, a white phone screen won’t reflect less light as you presuppose - it’ll generate more heat internally - unless you cover the screen with white paint.
