Bias lights are more helpful when the set is small, and you sit far away from it. Otherwise, it is pretty much unnecessary when you sit the proper distance away from the set.

Do you see any bias lights in a movie theater? No! The small lights you see down the isleways are not nearly enough light to counter what is happening on that big screen.
WHICH IS THE POINT, the movies are a BIIIIG screen.
