Ah, I see now that the lack of detail you've been talking about is due to shadow detail. I was thinking in terms of resolution/sharpness before. Unfortunately some HDR titles can be darker than others and end up crushing detail in the darker regions, this is where the environment settings can be useful but the majority of discs should require no manipulation once you've got it set up correctly.Thanks for all the info - yes I can confirm I have the TV Netflix set to Rec 709 and the 420 set to 2020. I finally got close and possibly better than the Netflix picture by adjusting my 420 picture mode to the "Light Environment" mode using the HDR mode (I tried also the SDR mode but obviously did not stick with it). This finally showed the intensity of the blacks and details within the shadows.
I'm surprised at this as HDR doesn't use gamma like SDR does. You'd best post in this thread Panasonic FZ series (802 & 952) OLED Owners Thread and ask owners what the correct settings are for HDR content. I believe your issues are related to your TVs settings rather than the 420, and not having any experience with Panasonic TVs i cant help you there.The Gamma setting is accessible via my OLED (set at 2.3) in Pro 1 HDR mode as normal via the advanced settings.
The Panasonic players do not officially support Atmos via Netflix and unfortunately you wont know if it's going to work until you connect it to an Atmos capable receiver.Any idea on the Netflix Atmos point?
