It's Game Mode itself that isn't responding the way we would expect/want it to.
Agreed. And since it can auto-detect the change from using BT 1886 (what we currently call Gamma)* for SDR to ST 2084 (the PQ EOTF) for HDR - and it already auto-changes the gamut - then it's certain that Game mode doesn't turn off too much processing in order to be able to auto-detect the changes in the incoming signal.
And thanks for clarifying again that Game Mode does indeed process HDR properly. I've started referring to the separate HDR picture settings as a profile rather than a mode, hoping to not add to the confusion.
Excellent idea, thank you
sir! Profile is a good one. So some Modes have two Profiles.
The other one that gets called a "mode" is the "Input type is set to a PC" one.
* I really like the way that the 2017 models have Gamma as a heading and then the 3 "flavours" - HLG, ST 2084 and BT 1886 - as the options inside that heading. It does mean people will have to learn that BT 1886 is the SDR gamma they've used all their lives, but that's a minor thing, I really like the way it makes it much clearer that the ST 2084 system is the HDR equivalent.
We know that on our 2016 models that when processing HDR, the "Dynamic Contrast" control behaves completely differently (to how it does when processing SDR) and it changes the EOTF curve in some way to make HDR images look brighter. At the same time, we've got this other control called "Gamma" which can't be adjusting BT1886 (because that system isn't in use) so it must be being re-purposed and *also* be tweaking the same EOTF curve, but presumably in a different way.
It's all rather opaque.
