I don't think this demo uses your monitor's HDR. You can test by pausing the simulation, then paint your whole screen with the pointer. Your screen is now all white. Compare brightness with a regular white page, it's the same brightness. I have an OLED display too. SDR content looks really good on OLED displays because of the incredible contrast. It might appear HDR but is SDR.
