I'm no expert on CA bats but i do rebind the handles on a number of brand new ones imported from back home by Pakistanis living in Peterborough, they bring them to me still in the plastic wrap and ask me to sort the binding out.
The sticker on the edges looks wrong to me. There also should be a circular (i think hologramed) sticker depicting a bat mallet carrying the words 'fully knocked' on the front of the bat, which is not there. The 'A' sticker on the back also seems poorly applied.
Does the grip have a contrast coloured ribbon where you put the top hand, with CA branding? Does the toe guard say TRD?
All of this seems quite typical of CA bats though, poor finishing, sticker inaccuracies and weight discrepancies, not sure how anyone can 100% say it is fake when there is so much variation in the genuine product. On the other side, the willow looks good.
