I cannot tell the difference between backyard eggs and fancy store bought (organic, free-range) eggs, but I can tell the difference between that set and industrial store bought eggs.
My expectation is that what you're tasting is the difference between a very fresh egg and an older egg; there's no doubt that's real (older eggs aren't even functionally the same as fresh eggs).
