It only has one saved setting and that is for 'Game mode' so when you switch HDR off with the higher contrast colours and what not enabled, it's still there and makes the pictures oversaturated. And these days TVs don't need messing with that much to get the best picture.
Uncharted 4 and The last of us though. Look very washed out. Hardly any colour compared to the SDR mode. And I'm not the only one with the same issue.
First Japanese RPG for me. seems a bit hand holdy so far. And stops to text boxes every few seconds. It's slowly opening up but I'm not feeling the magic so much with it so far.
I've got a Sony 4k HDR TV. I don't get the hype behind HDR. In many cases it actually looks worse unless you mess with the settings every time it switches to HDR mode. 4K though is a very, very clean image.
