In VRChat VR mode, the volumetrics only appear on the far left of the left eye (see image below). You can kind of see the fog blending between green/blue on that far left edge as intended, changing the density also effected this area of the screen so I am fairly confident it is the volumetric effect rather than some other unrelated visual bug.
Otherwise, everything is working generally as intended using a 2D camera or non-VR mode (see bottom right of image).
(Not sure if this is user error or a bug!)
