an AUD source of an official release is fine here because there is no competition when it comes to sound quality. fans who have already bought the official release will have interest in the fly on the wall unedited open air recording, and those who have not yet bought the official recording yet will be able to get a taste of how good it would be to own the same show with perfect sound quality and support the band.

also, an official release is not just SBD quality, it is better because it also includes mics on the audience to capture more of the excitement that doesn't always get across in a dry airtight SBD.
