What difference would it make if it did? Since when are freight trucks and warehouses heated? When the paint leaves the factory it travels via an LTL freight carrier or in smaller quantities by UPS or FedEx, none of these vehicles have heated cargo compartments. A semi trailer is subjected to the extremes of the weather...subzero cold to boiling heat in the summer sun.
A true emulsion should be fine, (typical heat is worse than cold) if the components separate they can be remixed without ill effect.
If you want your paint delivered to you in a climate controlled vehicle or shipping container...dig deep, its gonna cost you plenty.
If the label has no "Protect From Freezing" on it then you have nothing to worry about.
