The new feature called Differences will be available in On Demand Recovery for Azure AD starting on April 27th. This new feature will show you changes to a user or group by comparing the backup to live Azure AD\O365. It can be found under the Differences tab between Objects and Events in the Backup and Recovery Dashboard.
Please test it out and send me your feedback in this discussion.
