It's a good idea to only use DJI OEM props. DJI does not make full carbon fiber props. They do make props that are reinforced with carbon fiber though:

Those props are 9443's though. You'll get better performance out of 9450's. And, if you have a P2V+ version 3
(or if you upgraded the motors), you should only use 9450's.
Running with balanced props will ensure you're flying efficiently and not adding jello to your videos. All of the DJI OEM props I ever bought were a bit unbalanced. That said, I'm betting yours aren't 100% balanced either.
The SpeedyTM prop balancer works well for me. It's also a nice choice because it comes with the balancer and rod.
