The Microsoft Store is making the determination for the ability to download packages from the Microsoft Store source.
This isn't really a bug for WinGet, but WinGet is how folks would encounter this situation.

The metadata is displaying "true", but in reality, it's "false" when WinGet is calling the APIs used to download the package.

We've reached out to get the bug fixed in the metadata response for winget show. That will not change the behavior in this case. The package will still not be available for download or offline installation.
