Need Help with Screen Shaders

I'm trying to recreate the Sandevistan from Cyberpunk which, when activated, applies this glitchy blue tinted effect to the screen. To achieve this, I'm trying to use screen shaders on a sphere parented to my avatar's head (which I will only enable if IsLocal is true to not bother other players once I actually figure out this issue). The problem is that this effect only shows up in the Unity editor and the photo camera, and not on my headset/desktop monitor.

The effect functioning in the photo camera tablet, while everything outside of it remains unchanged.

I've tried this with two separate shaders now (StereoCancer and ScreenSpace_Ubershader) and both yielded this exact same result. Any help is appreciated, I will supply more info if needed.
