1 hour prior to planned departure at XA:45Z; we received a Final Dangerous Goods summary after ACARS initialization. That summary had the exact format and information as the planned Dangerous Goods summary example in the FOM. 5 minutes before departure I asked for the final Dangerous Goods summary. After a delay; at XB:52Z; we received another final Dangerous Goods summary. That summary looked exactly like the format in the FOM for the Final Dangerous Goods summary as it included the 'Hazmat loaded by' section.  My concern is that there are two 'Final Dangerous Goods Summary' notifications with different information.  Should an FOM revision be made to reflect the current procedures? In the future; is it acceptable to pushback with a 'Final Dangerous Goods Summary' that doesn't include the 'Hazmat loaded by' section?
B787 Captain reported two Final Dangerous Goods summaries with different information formats provided to Captain.
