Just finished watching both simultaneously (the Deflickered cam and official Digital Download) - there were no additional scenes - nor were there any scenes missing (both ran at the same length too). I didn’t notice any changes to the dialogue or music - nor any changes to what was on screen.
There a bloody amazing difference in quality between the two (obviously), as well as colour, detail and being able to see the emotions of the actors - really enjoyed watching it (them) again 😃
