My 77" LG G1 looked awful out of the box. A few hours of HDR content and a pixel refresher later, and its the cleanest OLED panel I've seen.
It may not work perfectly for all panels, but will most likely improve them a lot. You should also do this every 1000 hours or so to clear any possible pixel issues that develop over time. This also applies to Sony OLEDs.
