Cinema User..... do you mean Cinema Home? Or Cinema with tweaks? I AM coming around to this observation, as I said. I just need to get the color temperature off Warm. (yuck) The HDR is too dingy/muted in some scenes on Standard. Yellows especially. Don't get why the had to change so much over the C8. Maybe its panel variance or actual improvements.
In general, Cinema is one of the most accurate PQ modes
Cinema home is a little brighter.
Im not trying to convince you but every pro AV review have stated there are no significant changes (except HDMI 2.1) from the C8 to C9. Color volume and HDR is refined. DTM reveals more detail but it also tends to
darken or lighten the PQ. Most of us agree here the C9 is a nicely refined C8.
