It's all trade offs in that case and his reasoning for using these less than ideal settings was to show a 'worse case scenario' of sorts where correct tonemapping is important But you can see how none of the three sets actually displays these images correctly. Sony's approach of clipping above the peak and tracking the EOTF curve accurately is actually more typical of mastering monitors than TVs where this is the desired behaviour.
Sony actually chooses something closer to the LG approach on the ZD9 though Sony's justification there is they wanted the ZD9 to be a 'consumer version' studios can use to understand how a TV might tonemap content that is mapped to a TV.
It also is important to note here that peak brightness does indeed matter and all of these displays lose detail in some way or look inaccurate. For LG it's expanding dynamic range on the low end to keep distinct steps on the higher levels hence why it is dimmer.
This is a great explanation. In the video in my previous post, you can see the Sony handling above black details a lot better than the LG which is crushing those same details.
