There could be a new crater by an asteroid that impacted the moon this morning. The crater is big, but not quite big enough to be visible on the blurred "real" image you shot this afternoon. After Samsung's alogrithm enhances the picture it has a level of detail in which the crater /should/ be visible, but since that enhancement is based on older images, the cater remains invisible.
This situation may seem contrived, but it is actually quite common that people disagree about details that were present at a certain event and try to resolve the disagreement by referring to photos. Now photos can nolonger be trusted as arbiters.
It doesn't even have to be a new crater. The moon wobbles throughout the month so that the part that faces the earth is slightly different through time. Combine with how close the moon is to the earth (which varies) and the amount that is lit up, each day's picture of the moon is fairly unique (at least unique enough over a largish data set).
I would hope that their enhancement software pulls the current timestamp and synthesizes a picture that would be the same as what would be taken from a real high resolution / telescopic image at that time and place.
