WAIT i think i know what your talking about.... you mean if you press shift + s or w

then scroll in as much as you can... there are colorful circles or 'holes'?
I think I know what he is talking about.
If you go farther back in Toribash, you find a black/grey ground.

EDIT: Yea that.
Hm, well my guess is that the shaders colors need to blend somewhere... and thats like, the starting point for the colors and its a light backround, the colors might be a little off.

its a guess.. a bad guess.
I think i figured it out.....

now you see, if reflection is on... it GREATLY affects the floor color.... if you are that high up, you aren't able to see the reflection.. Therefore if you are at that height you are seeing the true floor/sky colors. untainted by reflections and such... maybe?
