I stand to be corrected on this one but wasnt ZZE one of the Boeing test aircraft? I know one of the first BA 777's was. This could mean it's feeling a little more worn out than others.
You can see it's history here .....

first flight Dec 1995 and del'y to BA in Jan 1996 so no test flights there I guess .... it did spend 6 months at Boeing in 2002 ?......
There must be something major wrong with it I would have thought....
