Inverse-square law; doesn't really apply...

The 'inverse-square law' only really applies to point source illumination.

A typical display/screen - viewed at normal distance(s) - is very different.

However - there probably is some effect relationship corresponding to how much of the field of vision is occupied by the screen - which would be a function of the screen size and the viewing distance.
