I've loaded and extracted the Grace Demo site on my hosting twice now and what I get is a base Protostar install. The weird part is the file manager in CPanel shows the template and files in place but Administrator and front end show no.
I ran extension discovery and installed those but this doesn't give me the demo site just the template over a clean install.
Am used to restoring an Akeeba Backup for a quickstart so not sure if I made some error or something else happened. Sure isn't the demo site though
