Post-Processing or Fullscreen Image Effects on Quest

Has anyone successfully written a fullscreen image effect in Unity that runs on the Oculus Quest?

Assumptions:
  • We want to (have to?) use Single-Pass rendering.
  • Post-Process Stack v2 is, to the best of my knowledge, unsupported (and will never be supported) on Quest.
  • We are not using the Scriptable Render Pipeline

If you can get away with it just draw a quad in front of the camera and use framebuffer fetch (https://docs.unity3d.com/Manual/SL-PlatformDifferences.html) to read the existing color and modify it. This will be many times faster than a traditional post processing pipeline on mobile, and works with any rendering settings. The only downside is you cannot sample pixels at different locations, so no blurring or distortion.
