@OlympusMons Thank you for reaching out to Microsoft Q&A. We apologize for the delay in responding to your issue.
I understand that you want to know how the Blob public access works. To clarify this, please refer to the below table:
As seen from the above table, even if the Storage account itself is disallowing public access but the access level for Container/Blob is set to Container/Blob level public access, there will not be any public access allowed for the Container/Blob.
Only when anonymous public access is permitted for a storage account and configured for a specific container, then a request to read a blob in that container that is passed without an Authorization header is accepted by the service, and the blob's data is returned in the response.
Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
