To answer everyone's questions and to put things in perspective I want to say a couple of things:
1) I don't know much about sonoftumble but his calman scans look "OK". Not actually measuring his set, it's not possible for me to tell if his calibration settings are correct, especially the CMS. The whole point of referencing his settings and others who "advertise" them, is to let everyone know, especially users who have no idea of what they are doing and are looking for "advice", the flip side of using another set's settings and the almost certain result of making whatever you have worse even though it might look better to your eyes in the beginning. Remember your brain equates change with better. If there were some "magic" settings that worked on every set, LG would put them in at the factory and that would be it. lol
2) As someone mentioned above, there are many users here who we know nothing about their experience, equipment, etc.. so their posts should be used as a "suggestion" or settings to think about, discuss, and how they may work but not something that you absolutely have to do to get a better picture. There are some professional calibrators such as Chadb and D-Nice and other experienced home calibrators who you can definitely take what they are reporting as pretty much fact. But again, you will never see them "advertise" calibration settings. What you will see are suggestions such as experimenting with the Brightness control to get better near black, suggested Calman settings, some experience setting color and tint, white point etc.. They will post scans to back up what they are saying on occasion as well.
3) As far as the red push on these LGs, my suggestion is if you see it and it bothers you, either calibrate the set or go into the 2 Pt high and lower the red and then blue 1 click at a time until it becomes unnoticeable. Remember when you start lowering red, blue will rise so you may want to try -2 red and -1 blue, -4 red and -2 blue. Again totally not scientific but if you are going to do anything you can experiment with this. I would never play with the 20 pt without equipment because doing so is like doing surgery with a blind fold on in the dark. As far as the one user stating that he was having trouble calibrating his set. The meter shows one thing and his eyes show another. If you have everything set up correctly and everything is set to D65 and balanced and you are still seeing red or green white then there is something wrong with your eyes or your set-up. Remember as we get older we start to see white getting towards yellow.
4) For the guy adjusting the HDR CMS settings, I never touch them unless they are really out because red is totally broken. LG knows this and it's not getting fixed for whatever reason.
5) For the guy with the gamma question, this is totally subjective, there is no right or wrong answer. For me i like 1886 for dark room and movie viewing and also calibrated in a bright picture mode.
Finally i just want to leave with the message that LG has done a lot of great work to make this consumer TV as good as they can out of the box. If you are not going to get your set calibrated, use one of the Expert picture modes and just adjust the OLED light to your liking, if you turn it down low, try raising the brightness one or two clicks buy not over 52, adjust Tru Motion if you need to and enjoy the set! And remember that these OLEDs are not perfect so there will always be some slight banding and tinting but it shouldn't be so much as to distract your viewing with normal content. If it does, get another set.
