I have to disagree with you on this Alister, because of gamma and the responses of displays the total range may be the same but the way it is represented can be totally different.

So if a monitor can manage 8 stops and the scene is 8 stops and if the brightness of the monitor can match the brightness of the scene, in the same environment both will look the same.
