Your living room will be different to the WHF test rooms, different lighting levels for example. The room size,colour,decour and lighting level will have an effect on the settings, WHF test rooms might be softly lit and need less brightness/contrast than if the tv was in a brightly lit living room for example. What worked best in WHF towers might be miles of the calibrated settings you end up using if you set it up with a test disc like the THX optimiser.
The WHF settings might be handy for reference but you might find your own calibrated settings will work better in your own room.
