Please describe your issue in as much detail as possible:

If the Steam Deck is connected to a non-HDR monitor or to a monitor via a Dock / HUB without HDR passthrough, the HDR toggle does not visually reflect the current state of the device.

1. The Quick-Access Menu (QAM) and Display settings are visually greyed out but the toggle is shown as visually enabled (aria-checked="true").
2. The Quick-Access Menu (QAM) does not indicate the Display's HDR support status similar to the Display settings (or like the QAM's VRR option).

Quick-Access Menu	Display Settings

This would be visually consistent with other options such a VRR (in the QAM) and HDMI CEC (Display Settings).

Steps for reproducing this issue:

1. Connect a Steam Deck to a non-HDR monitor.
2. Navigate to Steam -> Settings -> Display and scroll down to Enable HDR.
3. Press ... to open the Quick-Access Menu.
4. Navigate to the Performance tab and scroll down to Enable HDR

Affected Platforms

• LCD / Jupiter: Yes
• OLED / Galileo: Yes
• Desktop Deck-like session (gamescope -e -- steam -gamepadui -steamdeck): N/A

Actual result

• HDR toggle is visually enabled when the option is greyed out. Option does not indicate that the current display does not support HDR.

Expected result

• HDR toggle is always visually off when the option is greyed out. Option indicates the HDR status of the current monitor to highlight why the option is enabled or not.
