Default Scopes, accuracy light or heat

Just wondering about the above after Sunday's GP. I have heard some saying the HEAT made their scope read high / low. Others were saying it was the light contrast causing problems.
Myself no exspert in these things think it's light. A little history on this back in the late 80s we used to carry the old type light metre. I bought mine from a jumble sale, the idea was press the button and match scope px to light metre. If the metre went 1/4 way up scale I would allow a yard on px and as it went further up the scale more yards.
So the question is does LIGHT or HEAT effect the PX.
