Local or Global?

Local dimming refers to just specifies different parts of the screen that can be dimmed. You should look at that this as it being close (local) lighting.

White Balance is used to describe how warm or cool the picture on your TV will be. This is important because it is too warm it might appear brighter and it is vice versa for a cool screen. If it is too cool then it can appear darker.

Color Gamut refers to the wide range of colors on the color spectrum. This is important because you do not want colors that are dark to be so dark that it disappears in the background. The same goes for the white. You do not want your light colors to blend in with light backgrounds to the point of disappearing.

Black Levels control the overall brightness of the TV screen. This is like the glue holding the color gamut together. The Backlight in your TV illuminates the screen from behind. It brings forth the light colors. When this is turned up high it makes the lighter colors pop and the darker colors really stand out against it.
