> since nits indicate the amount of light (candles per square meter) hitting a board 1m from the source, I think I can see how you've got here but that's not correct. It's about the light emitted per square meter of the source, not a measure of the light hitting a board some distance away. Moving a screen closer doesn't make it more intense, because as you move closer it covers more of your vision. Total light increased, but not more intense.
