The factory fitted screen protector on my Fold3 also delaminated so I peeled it off which does not invalidate the warranty. However the caveat is that if the screen is damaged in the act of peeling it off then that will. However it's an easy process to remove.
I use mine without one and it's been fine.
Yes Whitestone Dome do sell that variant of screen protector and from what I've read they are good albeit a bit fiddly to fit.
From what I've read in the past threads some Samsung Service Centres actually in some cases replace the whole screen and battery instead of installing a new screen protector as I assume they don't have a machine to fit a new protector or don't have Protectors.
Whether that's still the case I'm not sure but I didn't want that for my Fold3 for the sake of a plastic screen protector.
