I ended up installing Nova (it's what I've used for eons on other devices). It works fine and has the benefit of running the same layout on both the cover screen and the main inside screen. Less laggy than One UI home, plus custom icons and gestures.
Thanx for the reply, I really appreciate it!
I knew Sammy started preinstalling a protector on their high end devices, (my Note 10+ & 20 Ultra had it), & the ZF3's main screen had the newer, more durable protector preinstalled, but I wasn't sure about the outer screen until now. I preordered the ZF3, (it'll arrive in the next couple days), & if I would have needed to order a protector for the outer screen I wanted to have it in time to install day 1, (I wasn't keen on using the phone without it), so the forums confirmation was a huge help!! 
(the ocd is pleased, lol 
)!
