You are trying to use the exception (SIN-LAX, SIN-NYC) to prove the rule. Sorry that dog don't hunt. As is pointed out in the debate you cite on the vast majority of the city pairs the 787-9 is about 6% more fuel efficient than the A350-900 on a pax-km/liter of fuel.
The 787 also has the added benefits of lower cabin altitudes, fresh (no engine bleed), humidified cabin air and a superior FCRF.
Pardon me if I don’t take a blog that has been in existence for 5 months as gospel regarding airplane economics. Heck even the same blog has an article about fuel efficiency that says the 350 is the worlds most fuel efficient aircraft.

From post #36 in that thread based on performance models the fuel burn difference is very close when comparing the same payload, over the same distance.
Im not disputing that the 787 is efficient, but so is the A350. It just depends on what size aircraft you need and how far you need to fly it. Will the 350 burn more? Yes. It is a bigger airplane with higher thrust engines, but the 350 can carry a larger payload then the 787, and carry that payload further. So if marketing thinks they can profitably sell the increase in seats on a 350 vs the 787 the fuel burn advantage on a particular route of the 787 is offset.
And the 350 has the same cabin altitude of 6000’ and same on the humidity so no difference there. And can one really tell if it’s bleed air or not? The 350 is a quieter cabin as measured by 6 DB according to Airbus (

As far as the FCRF, since we don’t have them, kinda hard to compare don’t you think? And don’t tell me because it’s UAL ALPA disapproved that it isn’t comfortable. The 350 doesn’t meet the FAR requirements for square footage, that doesn’t say anything about comfort levels. And to date the CROC and MEC have not given the company any relief from needing to meet the FAR (by not asking for a waiver from the FAA) which I totally support.
