Do you have a link please?

GE convinced ANZ to change over from the T1000 to the GEnx for fuel burn efficiency reasons as stated in the article.
Now, either that's because the GEnx is already more efficient by a significant enough percentage, or because the Ceramic Matrix Composite PIP will be ready to go by the time ANZ gets their 787-10s. Either way, given the proposal for an A350 NEO, I think it's safe to say GE is working hard on competitive improvements, and knocking this idea is probably short-sighted.
The A330-800 has a brochure range of 15,100km. If GE can provide a 4-5% fuel burn improvement, that could potentially rise to the 16,090km range of the A350-1000, making it a VERY competitive "thin" route ULH craft.
If Boeing's 788 improvements don't push its range that high, Airbus will be unchallenged in that market segment.
