Surely the AI picture detection is for people who don't want calibration? After all, an accurate picture doesn't change depending on what kind of content you are watching does it?
The AI malarkey by LG, Samsung, Sony, Panasonic etc is just marketing buzz nonsense! To attract the normal buyers who don't have a clue about picture settings or how to set up a tv properly.
LG's AI picture detection and all the other AI stuff is nothing like calibration. And it doesn't deliver a image as originally intended like LG wrongly claim.
It's the complete opposite - An inaccurate picture as it uses artificial digital noise reduction, artificial detail enhancement and artificial edge enhancement sharpening.
As others have previously said turn off all the AI junk in the picture settings

if you can't get it calibrated then use Filmmaker mode for dvd, blu ray & 4k blu ray movies. Which gives a very faithful authentic picture as the director intended.
