I can't say that the fix we pushed out will fix the LG C9 but I can tell you that the fix corrected issues being observed on the W9; specifically the LG OLED65W9PUA.
The fix is mainly for display devices that have an external connection box (like the LG "Wallpaper TV" or the Samsung "The Frame" displays).
