Home screen Dream UX problem!

[HV2]

I saw in the sammobile site that there are APKs for S8 apps looks and features. So I updated all my apps but now I can't get their old looks! And the launcher is on the Dream UX not on my Grace UX!

Go to the touchwiz app>select 3 dots on top right corner>select uninstall updates...
It goes back to original one.
