I'm using Auto for everything (the Oppo performing any scaling to 4K), with TV Led for DV. I should specify that any raised black due to using a custom 1D LUT (CalMAN AutoCal) remain. I switched to an uncalibrated picture mode on the C9 to check for raised blacks.
Thanks, don't really understand the last part, are you saying uncalibrated picture mode raised blacks are still a problem be it from internal source on TV or external device such as oppo203/apple tv 4k.
I hope LG fix this once and for all.
