My 2 cents.......
CF being more rigid , will likely convert more energy into lift , than a flexy plastic prop. Some energy will be absorbed in the flexing , but whether it increases flight time , I doubt very much . I have some aftermarket ones , not tried yet , but I would expect them to respond to control inputs a bit sharper than softer plastic ones . Whether it be enough to quantify , or even notice , are 2 questions unresolved as yet . They were off Ebay , and as I've got plenty of O.E. spares ,may not get used , unles I have a bad prop day and run short .
