I see, i was expecting that filmmaker mode would make the picture look a bit darker, so then the question begs what is Filmmaker mode doing differently than Cinema under the hood? Do both modes target the same whitepoint OOTB? Does filmmaker mode disable any processing, are any picture settings options grayed out in filmmaker mode that are accessible in Cinema?There s zero peak luminance difference between HDR FILMMAKER_MODE and HDR Cinema. If you want measurements of known inaccurate video modes, like Cinema Home, you will have to look else where. Accuracy to content creator's intent is and will be my sole focus.
