### Describe the Bug

![Image](https://github.com/user-attachments/assets/6f39f834-3567-4d88-8e1e-cf7890b1c930)

I am running into problems where a non-HDR client will turn off my HDR host as requested/expected, but upon full disconnect, it will not turn back on the HDR, but all other parameters (resolution+refresh rate) are reverted successfully. 

### Expected Behavior

Upon disconnect, HDR should be reverted to turned on state, if host has HDR on.

### Additional Context

I reported it here before https://github.com/FrogTheFrog/Sunshine/pull/2#issuecomment-2565278389 
But I was not able to respond to @FrogTheFrog on time.
