We bought an LG C1 55" last week and I've just started looking around the 'net for calibration advice.
I just found this recent YouTube item by well-respected, long-term TV adviser, Vincent Teoh. Seems that C1's and G1's built from October 2021 onward have a software problem with HDMI 2.2 affecting their playing of 4K content from XBox Series X, PS5, Blu-Ray boxes etc

LG have acknowledged the issue and have told him that it will be fixed with an upcoming update of WebOS.
Our C1 received an update to WebOS 03.20.80 last night. It seems this is the fix that I was referring to above.
Just realised I inadvertently said HDMI 2.2 in my earlier post - should have been HDCP.
