Is it just a change in the gamma setting to like a -1 or -2, or is it a combination of this and choosing a color mode like Cinema, or even tweaking the HDR setting to an Auto 1 or Auto 2.
Any guidance is greatly appreciated. As an FYI, I’ve tried all kinds of settings for this pj from Harpervision, Oledurt, etc. and while I do have some presets that I like I want to make sure I’m setting everything up correctly with the UB820.

I happen to take a couple of pics (Aquaman 4K disc) last night with the HDR Optimizer On and Off on the 820. These aren't the greatest pics or the best example, but it does show a difference, so hopefully it helps. With the Optimizer Off, the white was blown out. With it On, you can see detail in the white. (It is more noticeable in person, or course.)
Super White: Off
Dynamic Range: Auto (Bright)
Dynamic Range Adjustment: 4
*The thing I found out was that I needed to have Super White Off in the Epson to show the effect of the HDR Optimizer. With...
- Super White On and HDR Optimizer On = less detail in white, similar to the 1st pic below
- Super White On and HDR Optimizer Off = detail did show in white, similar to the 2nd pic below
I may be wrong, but from what I read it seems that with Super White On, the Epson tries to prevent blown out whites. So with SW On, along with the Optimizer On, it does not produce as much detail in the whites because they're both trying to prevent blown out whites. I'll test some more tonight on that theory, but maybe others can too. Basically the HDR Optimizer worked better when Super White was set to Off in the Epson.
My next thing will be to have Super White Off and the Panny set to output SDR2020. I haven't tested that yet. (I did watch Aquaman and Bumblebee with the Panny outputting SDR2020, but I had Super White On for those movies.)
