The scaled adjustment increases the brightness by the amount proportional to the color's numeric value. In your example the default value for the color is OxFFFFFF, which means that both of the adjustment methods will produce the same effect. If you choose a color other, which mixes different amount of each of the colors you will see the difference. Generally speaking the scaled adjustment is better if you need to preserve the color tone.
