I agree with most of your post but OEB was the only ex Asiana B744 that QF bought second hand which is why its systems are different from the rest of the fleet. OEC and OED were ex Malaysian airlines and I understand that the lousy paint job that you accurately described was done by MAS paint facility. The resulting cracks in the fuselage skin was severe and could have had major consequences. As far as I know there has not been a similar problem with OEB.
Good luck to all QF HM guys - I hope the announcement is not as bad as we fear.
