With the 2017-08-03 snapshot ISO it appears this is not the case. Perhaps one should first connect to the internet before starting Software center for the first time?
Yes, GNOME Software requires an internet connection on its first run, and display a "please wait" message while it is refreshing. If none is there, I don't know exactly what happens, but I guess the SC being empty is the result.
There is no need to run apt update manually.
