I recently bought an LG OLED TV from their C2 series (OLED55C2PUA to be exact). It was quite difficult to find reasonable settings to get a faithful image online, so I spent a few days tweaking things until everything looked OK to me. I hope you find this table useful when you end up searching for settings for your TV.
Step 0: Ensure you use HDMI 2.1 cables
To get the most out of your TV, you must use HDMI 2.1-compatible (also called “Ultra High Speed” or “48Gbps”) cables. Test your connected consoles and other devices after this setup sequence to make sure all expected capabilities are functional, including 120 Hz 4K video.
Step 1: Set up your TV
This step is tedious and repetitive, because you have to apply these settings once for every new input format that comes down the wire. I have no idea how many combinations of formats (4K, 1440p, 1080p, UHD, Dolby Vision, HFR, 60 Hz, etc) get assigned their own settings, but I spent dozens of minutes setting everything up over and over again because my game console decided to throw a different format on the screen. Be prepared to keep applying these settings until they stick.
General settings
I apply these settings to all my inputs. Skip over entries that are disabled.

For inputs connected to game consoles, I like to enable Game Optimizer to reduce latency and support variable frame rates. Apply these settings in addition to the ones above.

Step 2: Set up your devices
Now it’s time to set up your connected devices. Game consoles, especially, need to be calibrated to take maximum advantage of your setup. Here are the settings that work for my XBOX Series X, PlayStation 5, and AppleTV 4K.

Step 3: Enjoy
These settings yield high quality images for me, free from artificial boosts and trickery. Dolby Vision looks great. Games run at 120 Hz without issues.
If the image suddenly gets way too bright or otherwise looks much too punchy, go through the TV setup steps again. Your TV has likely encountered a new video format and has reset to its default settings.
Have fun!
