Steam and Epic Store have dark grey backgrounds - vertical banding is very visible there on C3 and also in dark games when moving/panning a camera. I have no banding on my AW3423DW qd oled in the same scenarios. I guess I won the panel lottery with my DW and it doesn't want to be replaced with C3
Shame as in other aspects (4k, size, working space, apps, movie watching) C3 is perfect. Settings are not the reason - I set them up according to one of the best settings guides for LG oleds there is online. What I am asking is how big of a chance is there that if I decide to keep it and sell DW, banding on C3will improve with time? I have a return period of 2 weeks to decide.
