Hi wesinator, thank you for taking the time to report this bug!
You are correct, this settings screen is not very coherent and we're looking at ways to make it better. When the Camera permission have never been requested, this screen allows you to enable it. However, once granted, you can only revoke the access via the OS level Settings.app. For the tie being, as a workaround, if you want to disable Camera access for Orion, please got to "Settings.app → Aps → Orion → Camera".
Thank you for your help in making Orion a better browser!
