I experienced the same issue with Unity 2021.3. After many hours of profiling and debugging, I switched the OVRPlugin to Legacy LibOVR+VRAPI backend which solved my performance degradation issue. Based on my experience, I would not recommend using OpenXR at this time.
In terms of the Extra Latency Mode, I noticed the same issue. The LAT metric in the OVR Metrics Tool is 0, when a value of 1 implies that it's activated. This occurs even when I enable Phase Sync in the XR Plugin; which from my understanding is how you enable Extra Latency Mode now (i.e. Extra Latency Mode = Phase Sync).

Hey there!
That's some awesome looking info, but admittedly a bit outside of our wheelhouse to help with. Fortunately, many developers are currently working with Unity and have an entire section of the forums dedicated to what they're doing. Here's a link to that forum!
Swing by there and make a post. You'll find much more assistance and relevant information there. 🙂
