[Gimp-developer] Luminosity in LAB does not agree with Wikipedia or Matlab

     In this article http://en.wikipedia.org/wiki/HSL_and_HSV is displayed an image (http://en.wikipedia.org/wiki/File:Fire_breathing_2_Luc_Viatour.jpg) and its luminosity (http://en.wikipedia.org/wiki/File:Fire-breather_CIELAB_L*.jpg). However, if I apply Colors-Components-Decompose-LAB in Gimp, the image L does not agree. The same happens with Matlab.

     I'm not sure if this is an error in the program or a documentation problem. In the last case, for example, the LAB model of Gimp is not the CIELAB model, or the model is CIELAB but they use different white points.
