This looks perfectly accurate to me.

1) There is nothing to affect the amount of light returning from off in the
distance.

2) POV does things too perfectly, so you have an image of the perfect
hallway with the perfect lighting all the way down it.

3)  There is no variance in the lighting from each individual light... in
reality, some of the lights would be weaker casting lower levels of light.
In POV, and in this render, all the lights are equal.

4)  Dust and other things will add to the dim-ness of light seen way off in
the distance.

5) With regard to light cast by stars, if you were out in space with no
other bodies nearby, the light cast by all the stars combine would be
approximately equal.  Close to earth or within earth's atmosphere, you have
things affecting the "flavor" of light as well as a massive "star", the sun,
providing millions of candlepower more light than any star is providing.

6) With regard to the 1/4 rule, you have to look at the hallway... each
measure of distance down the hall reduces the size of the total number of
pixels each measure represents in 2D.  What light is available in each
measure is considerably less than that in the previous measure.  It is one
of those optical illusions played on our eyes that happens because we see in
2-D things that are 3-D.  Imagine if we had eyes on stalks sticking out from
our heads how much differently we would view the world we live in.

I believe to make this picture more realistic, you must program POV to use
random to vary the intensity and fade power of each light source.
