Even a 0.1% increase in fuel requirements is bad when airlines biggest costs is in fuel. Boeing and Airbus are spending billions just to get a 1% fuel efficiency boost. And the LEAP-1C isn't exactly the best engine on the market anyway, with the C919 already lagging behind it's Boeing and Airbus counterparts in range and fuel efficiency even with the LEAP-1C. Hopefully a upgraded variant is in the works.

Yeah. This is China first commercial civilian aircraft engine. So its normal it won't match even the fairly older Western ones like LEAP-1C. However its a great start. They will need alot of time and actual production service for the engine to be tested with feedbacks and fine tuned with newer upgrades.
So all this need years if not decades.

Footage started appearing last year of the Y-20 test platform flying with a CJ-1000 engine. I'm guessing the engines that have been delivered were only for testing. If so, then I'm not sure "production turbofans" is the correct term to describe those engines.

In the Western parlance, yes, they are production turbofans since their delivery indicates that there is a running supply chain. It may be a slow production but it is still a production.
