After further investigation, this appears to be partly a product of the OEM installer installing plasma-netbook instead of plasma-desktop. On installs that get -desktop, the Prepare for Shipping icon is present on the desktop, however, it is not on the -netbook environment.
There appears to be an issue where OEM is installing -netbook regardless of whether a system meets netbook criteria or not.
