Meh, I've watched bog standard HDR and movies with DV+ on my non calibrated LGCX and I can't tell the difference and I suspect the vast majority can't see the difference either, hell before I got my TV I had a load of settings and tweaks from Vincent T and others to apply/check and when I switched it on and watched some movies I figured why bother the picture was bloody amazing right out of the box.
It's like buying a 300hp motor and one with 320hp nobody is telling the difference except professional race drivers
