I quickly tested the behaviour and can confirm that I was able to detect the ceiling as GroundPlane however it was very difficult.
In our Core Sample, available here https://assetstore.unity.com/publishers/2448, we demo the GroundPlane feature and provide visual indicators for users to point the screen to the ground.
Hi,
I quickly tested the behaviour and can confirm that I was able to detect the ceiling as GroundPlane however it was very difficult.

I think this might help you, address the issue.
Thank you.
