Given that screens are always adding their own light, it’s impossible for a screen to ever be equally bright as a piece of paper next to it. The screen will always be brighter.

That depends entirely on ambient light levels.

All screens are brighter than white paper under moon light, almost none are brighter than white paper under midday sun.

And reading under the midday sun is painful, much more so than a bright screen.

If you haven't experienced before, I recommend it. It helps you appreciate just how bright direct sunlight is relative to other light sources.

Do what now? An entirely black OLED screen is certainly going to reflect less of the room’s light than a sheet of white paper. An OLED screen displaying white at 10% of its maximum brightness is also likely going to be less bright than a sheet of white paper in most rooms.

No because some surfaces reflect more of the light than other sufaces.
