No. The test under the Notifiable Data Breaches scheme is whether the breach is likely to result in serious harm, and remedial action taken quickly enough can mean there is no eligible breach to report at all. Speed matters, and so does evidence. A remote wipe command and no new cloud sign-ins indicate the device has not been used to reach your mailboxes or files online. They do not on their own show that files stored on the laptop were unreadable, so the assessment also confirms the disk was encrypted, that the firm held the recovery key, and whether the wipe was ever received.
