I took a look at Digital Foundry's video for recommended TV settings. We happen to have the same model so this was worth checking out:

Not sure I entirely agree with some of their presets though.
Warm over 40? That seems overkill.
Color Gamut on Normal instead of Wide? They claim it's a more "natural" color, but for me it feels washed out. I think I prefer Wide much more.
And I rarely see any commentary of Super Resolution. From near as I can tell, the games that wouldn't benefit from it don't look better or worse with it turned on, while the ones that do show a noticeable difference seem to have improved backgrounds with it set to at least Medium.
The ISF setting for movies also continues to confuse me. It seems you use ISF Bright or Dark depending on the lighting of your space. They mention offices and dark rooms, but what am I supposed to do with a small room that's somewhere in the middle, brightness-wise?
Lastly, they don't mention any settings for movies/shows that feature HDR, as some Netflix shows do. Not sure what my settings should be in that instance.
That video was before LG tweaked the tone mapping for HDR game mode.
Now wide is the correct setting. Before it wasn't.
Now you need dynamic contrast on. Assuming of course you are on the latest firmware.
B6 changes not quite as drastic as changes on my C6. Having said all that I'm loving HDR gaming on the C6, DC hasn't bothered me.
