I agree that ACAPS is optimistic, thus I also wrote this:

The margin is 1,600nm.

That's basically max structural payload, since ACAPS does assume a very light cabin. (ACAPS states 52t max payload, which a heavier cabin will eat into)
From the other thread which you linked:

...7t fuel will carry you 600nm or so.
According to your data source, DL's A359 can realistically fly 7,100nm, which means LAX-SYD is flyable with full pax and bags.
