I didn't want to include this in the main post because the demonstration is scuffed (I don't really know how to use Blender and the idea is not to be precise, but merely demonstrate the intuition) but in this clip I try to give an example of how insane a 161.1 degree field of view is.

From Twitter, Cog uses some sort of Motorola, though 3 different models are mentioned:

They have rear-camera FoVs of around 70 degrees reported in technical specifications.
You can see the vast difference between 70 degrees and 161 degrees.
I have no idea how "Mandy" accomplished this with their phone, but it's what's in the EXIF metadata.
