Features in S10 phone but not in S4 tablet

[cwy]

I got both S10 and S4 recently, and both have Android 10 and One UI 2.1. Yet on the S4 there is no option to put the brightness slider near the top, nor can it select multiple wallpapers for the lock screen. S10 has both features (pictured below). What exactly is preventing S4 from having those features, and can I get them back?

Tab S4 processor is based on note 8 which is SD835 and S10 is based on SD 855. May be software limitations based on hardware. Even Tab S4 don't have edge panel whereas Tab S6 have it.
