I can confirm DUJ6 is available, looks like just November security patches. I've seen many Samsung apps, including the store, updated to fit the ONE UI 4.0 style. I think the stable Android 12 version is around the corner for the S21 series therefore I guess before the end of the year we could get it as well :)
