Well, I was scathing in the recent survey - but I suspect my response would at best get "aggregated" (although I did give permission to pass on my MPC number)
But no, I don't see much changing for those of us who've been loyal customers for over 15 years, but who have usually turned right on boarding.
Unless and until there's a proper clear-out at the top levels of CX, I suspect CX will continue to wane, sadly.
