Amongst OLED and LCD displays with everything else (size, resolution, etc.) OLEDs intrinsically consume a lot more power than LCDs. Using dark themes help for OLEDs for reasons already stated here, and from what I have seen working on the display industry for several years, the power numbers quoted by OLED display manufactures often presume a dark theme when comparing power to LCDs.

Re: Dark vs. Light Theme Battery Stats on SAMOLED
#22there seems to be a lot of confusion over the efficiency of amoled vs lcd. In lcd, the power consumed directly depends upon the brightness, basically LED's provide the back-light light source and the colors you see on the screen are the representative of the kind of filters the light from the LCD had to cross to reach the surface. All lcd's are in this way passive displays. In an AMOLED display, there are three sets…
>> this is not an easy task and so explains why lcd's as of now display truer colors OLEDs have better color gamut and contrast than LCDs (without local dimming), making the colors better than LCDs.
OLEDs have larger color gamut, but larger is not always better.
“The Color Gamut is not only much larger than the Standard Color Gamut, which leads to distorted and exaggerated colors, but the Color Gamut is quite lopsided, with Green being a lot more saturated than Red or Blue, which adds a Green color caste to many images. Samsung has not bothered to correct or calibrate their display colors to bring them into closer agreement with the Standard sRGB / Rec.709 Color Gamut, so many images appear over saturated and gaudy.” – http://www.displaymate.com/Smartphone_ShootOut_2.htm

#23Switching to a dark theme and lowering the brightness also works quite good for desktops on UPS.
Lowering the brightness? Sure. Switching to a dark theme? Not so much. If you are using a LCD the color of your pixels doesn't matter. Ok, it might matter a little bit but not much and it's not as easy as saying that white uses more power than black. It might even be the other way around. In an LCD the color is determined by a liquid cristal filter that can be turned on or off and dimmed. The filter itself needs hard…
While there's definitely a difference, most likely because of dynamic contrast which might be negligible once you lower the brightness, the reason I switch to a dark theme is because low brightness white looks awful. Especially in a dark room. The monitor I'm using draws around 120 watts so lowering the brightness is a must.

what i meant to explain was, this.. the LED's fade over time. hence their color changes over time. and making two LED's display the same color and making them time equally is a very challenging job, some thing which current day technology is unable to do. yes, led's have a bigger color gamut, but the accuracy is definitely to b improved. gamut is the range, while accuracy is the exact color required i.e precision
