I don't think this is a meaningful or generally well-understood distinction. And I don't think that distinguishing social programs as parts or composites of "full blown socialism," which ostensibly refers to an command economy in which all economic decisions are made by a central, undemocratic state, is either helpful or accurate.
I say this because such social programs are neither necessary to nor the hallmark of either said command economy system or an actual socialistic system of government in which the economy is effectively democratized and workers maintain equity and decisionmaking powers in a given industry, firm, etc. For instance, a country could abolish state healthcare and people would still call it socialist because of restrictions on property ownership, investment, and market mechanisms. Meanwhile, a country could become fundamentally socialist, where all workplaces and industries are collectively owned and managed by workers and all state investments are voted on by the populace, and socialistically decide to forgo social programs like state healthcare.
