The Dark Pictures Anthology: House of Ashes - HDR Settings

This game does not seem to use the PS4, PS5 and Xbox HDR system calibration settings. 

Try to find data about the peak brightness of your TV on the site RTINGS.COM (value HDR peak brightness 10%). Before adjusting, make sure you have set the TV settings correctly.

Adjust the in-game Max Luminance slider to match your TV's peak brightness (slider values in nits). If your TV always does tone mapping that cannot be turned off, then set the maximum slider value.

You may have trouble setting the exact slider value. Not critical if you cannot set the exact value.
