I did some testing back in 2009 and I just looked up my spreadsheet and it really is hard to say definitively how much your TV will consume. At the time, my TV was a Samsung LCD A530 (I think). For example, usage based on input type (Component vs. HDMI): TV (Wii as input, Component) 48 to 68W TV (PVR Cable as input, HDMI) 84 to 104W Then you start getting into different TV settings for games versus TV, day versus night, and the list goes on. So what should the TV manufacturer put? Should they put the min consumption which is probably the dimmest setting? Or the highest? Or the average? It is an interesting question.

The default setting? The one shown most in the demo mode?

    I agree that a good test would have to cover a range of modes, but in this one specific instance demo mode is generally the one that will naturally be the biggest power waster as demo mode for modern TVs virtually always includes "crank the brightness and backlighting to ridiculous, highlight-crushing levels" as one of the settings.

    Wouldn't that mean that the product is showing content at its most pleasing to customers but with reduced power consumption?

      Random example from a moment's thought on how to cheat: demo mode typically runs in a store display, and likely has little opportunity for evaluation of audio (unless placed in a separate showroom as some stores do for a home-theater demo, but in that case it'll likely get tuned carefully). So, in demo mode, don't bother turning on the higher-energy portions of the audio system at all, because nobody will notice if the audio sounds tinny. And now you've potentially saved tens of watts in demo mode. (Also, note that demo mode typically tunes for most attention-grabbing in a showroom, which often does not provide the optimal viewing experience at home.)

The Samsung's feature from the article is apparently from 2011.
