I examined the female drive ends from my Gearwrench Spark Plug ratchet set. They are satin finished just like yours. None of my extensions from Craftsman, SK, Mac, Snap on, Matco, or Proto are chromed on the female drive end. Most are worn but, they appear to have been satin finished too.
I think the spring you refer to for the ball socket engagement, only purpose is to provide tension so, the socket doesn't flop around. My rotates freely but, I shot a little WD40 in there as I do with all of my ball type swivels. Mine doesn't make that clicking sound your first socket in the video did when rotated.
If you're still not happy or satisfied, I would contact Gearwrench or send the original set back to the vendor for a refund but, the set you have may be as good as it gets.
Nice video!!
