Sniper Elite 5 - HDR Settings

This game does not seem to use the PS4/PS5 HDR system calibration settings. The peak brightness in the game seems to be fixed and not adjustable. 

The main peak brightness limit is about 1000 nits. If your TV's peak brightness is very different from 1000nits, then use your TV's Tone Mapping modes.

The game also has a Brightness slider setting that adjusts the black level. It is recommended to leave the value at 50%. Decreasing the value may cause excessive contrast and reduced visibility in dark areas.
