Error in the display screen of the VR mobile SSR

There is no reflection at the center of the sphere, but there is it around.

Use UE5.5 ForwardRending,Mobile VR

at this angle the reflection is only the backside of the red sphere. there is a hint of the edge around but it literally can not reflect that. it’s screenspace.

This is a screenshot of the editor’s Android preview. The pictures above are the ones inside the VR helmet after being packaged.
