Steps to reproduce:
1. Open the attached user's project "URP VR 2023.zip"
2. Make sure OVR Metrics tools are installed via Meta Developer Hub and GPU/CPU Levels are enabled
3. In the Unity Editor, make sure OculusXR is selected as the XR Plugin
4. Build for Quest 2/3
5. In the Application, the overlay reports CPU and GPU levels as 4
6. Switch to OpenXR in the Editor and Build for Quest 2/3
7. Observe in the Application that the overlay reports CPU and GPU levels as 2 within the same Scene

Expected Result: CPU/GPU level reported by OVRMetrics is the same when compared to using OpenXR
Actual Result: CPU/GPU level reported by OVRMetrics is 2x higher than when compared to using OpenXR

Reproducible with: OculusXR 4.1.2 (2023.3.0b1)
Could not test on 2021.3.33f1, 2022.3.16f1, 2023.2.5f1 due to URP package errors after downgrading

Testing Environment: Windows 11
Not reproducible on: No other environment tested

Notes:
-Issue does not reproduce on a new project
-Issue reproduces with Vulkan and OpenGLES3
-Issue does not reproduce with OpenXR, GPU and CPU levels stay the same (reported by OVR Metrics at 2)
