The game is NOT using/applying Xbox, Playstation or PC HDR Calibration app settings.
The game has a very good HDR implementation by offering almost perfect black levels and precise in-game HDR sliders including a Peak HDR Luminance control (in nits value) which can go up to 10.000 nits with only a minor caveat: set Peak Brightness +10% higher the value of the slider to actually match it on the Display (after measurements)

If you have an LG OLED and:
> you're using Dynamic Tone Mapping or Dynamic Contrast:
Set PEAK BRIGHTNESS slider to: 4.400 (nits)
Set BRIGHTNESS (Paper White) slider to: 200 (nits)
> you're using HGIG:
Set Overall Brightness slider to: 880 (nits) or 1.100 (for G2/C4) or 1.700 (for G3/G4/C5) or 2.200 (for G5)
Set BRIGHTNESS (Paper White) slider to: 200 (nits) or 280 (for G3/G4/C5) or 300 (for G5)
If you don't have an LG OLED and:
> you don't have an HGIG option:
Set PEAK BRIGHTNESS slider to: 1.100 (nits)
Set BRIGHTNESS (Paper White) slider to: 200 (nits)
> you're using HGIG:
Set PEAK BRIGHTNESS slider to the corresponding real Peak HDR Luminance of your TV in "nits" (then add +10% to it)
Set BRIGHTNESS (Paper White) slider to: 200 (nits) up to 1.000nits or 280 (from 1.000 to 1.500 nits) or 300 (for 2.000 nits and above)
In all cases set HUD BRIGHTNESS to 100 (nits) and BLACK POINT to -0.2 to fix a slight black level raise introduced with the August 2025 patch.
BONUS:
On Consoles: use the "Performance" graphic mode for better smoothness and input latency
On PC:
- Use my UET Mod to improve performance, lower latency and have better clarity at the same time, all with no visual loss ;)
Enjoy!
