However, when I am playing HDR movies, I've noticed if you select "Wide" versus "Auto", the picture is not identical as I assumed it would be. Selecting "Wide" seems to provide more saturated colors, definitely noticeable. So makes me wonder whether the "Auto" setting is switching to "Wide" if the two seem different when playing HDR content. Does anyone have some knowledge on this setting?
Setting the Color Gamut to Wide will raise the Color saturation, but so some of us saw that there was a problem with the Red and Magenta HDR CMS in that it was out of spec and you couldn't adjust them with the CMS controls. We reported it to LG and their answer is to set the color gamut to Wide for HDR and that should solve the problem, meaning that Red and Magenta should line up and be adjustable. I haven't seen anyone verifying this yet. I would say, choose the mode Wide or Auto in which the HDR picture looks more accurate and natural to you eye until this is verified.
