Color processing environments on visionOS?

I have read about the various limitations in post-processing the camera feed (Metal is only in VR mode, no access to camera feed, etc)

Just to be clear, there is currently no way for a third party developer to do something similar to the 'Summer Light' environment, where a color filter is applied to an ImmersiveSpace in mixed mode?

...am hoping I am just missing something simple, thanks in advance.
