Does S3 Inventory include Overhead, Staging or Restore Object data?

Hi,

From my analysis, I couldn't find in S3 Inventory any of the data related to the Overhead, Staging or Restore Object ITEM OPERATIONs. I've been only able to find data that has the following Item Operations: DeepArchiveStorage, GlacierStorage, OneZoneIAStorage, ReducedRedundancyStorage, StandardStorage. S3 Inventory only provides data about the Storage Class. But I compared the data from S3 Inventory with other reports where we have the data detailed by Item Operation, and the missing data from S3 Inventory seems to be Overhead, Staging or Restore Object ITEM OPERATIONs. Is this correct to assume this is the expected behaviour?

Thank you!
