That may be true for AF and the La Premiere product. Never flown them before, and have thus never researched tickets, so can’t give an opinion either way.
However in OP’s case, when booking DL 7850/7851 between ATL and ICN, on 006 DL ticket stock, it clearly states you are purchasing a ticket in Prestige, not First Class. One might assume they are the same, but in fact they are not and each come with different benefits.
