Your system information

Steam client version: 1726683985
SteamOS version: 3.5.19
Opted into Steam client beta?: No
Opted into SteamOS beta?: No
Have you checked for updates in Settings > System?: Yes

Please describe your issue in as much detail as possible:

Gamescope defaults to an SDR-like ITM mode for SDR games.
Gamescope has an HDR-Like ITM mode (BT.2446 Method A).
That HDR-Like ITM mode is hidden behind a set of command line switches.
There is no way to toggle HDR-Like ITM mode per-game inside Gaming Mode.
This is a Feature Request to add a per-game (be it Steam or Non-Steam) HDR-Like Inverse Tone Mapping toggle plus related options (SDR nits, Target nits).

Steps for reproducing this issue:

I think it was probably intentionally disabled on the deck. Probably due to burn-in concerns. Remember the deck has zero burn-in mitigation.

And that's fine. That can be kept as default behavior.

This Feature Request is for Valve developers to incorporate the HDR-Like ITM method and related toggles in Gaming Mode; that would give users a valuable option to take advantage of the Steam Deck OLED's screen in more games than just those available with native HDR.

I can't argue with that.
