For this reason, "PC Mode" is not recommended for HDR Gaming, and as a matter of fact: "Game Console" input mode + "HDR Game Mode" + "Dynamic Contrast: Low" is NOT so dim as 2016 models, and it's bright perfectly good in a dark room.
To each its own, but, in my opinion, HDR isn't all that it's been hyped up to be, especially on OLEDs, which don't have the luminosity (nits) required to actually make a difference for that kind of content.
4K, on the other hand, is a much more noticeable improvement, especially for PC gamers. Consoles, up until the PS4 Pro and the Xbox One X, could barely output a true 1080p picture; and even now, with these mid-generation upgrades, very few games are rendered in native 4K, and most run at 30FPS or less.
As I said, if you're using your OLED as a monitor for a high-end PC, 4:4:4 chroma subsampling and the ability to run games in 4K at 60FPS with a full color range is more important than HDR. So, if you don't care for the latter, "PC" as the input label is the only way to go.

What version of Windows are you in? Are you on the Preview program or have the Fall update already installed, somehow? Because HDR implementation for the Creators Update was completely botched.
