Ear is different because the neck brace is pressing against it, distorting its shape.
Not sure about the nose. I do notice the pics are taken from slightly different angles. That could have an effect.
Some of the lines/wrinkles look different, especially the naso-labial folds (i.e. the lines between nose and mouth), but those are highly affected by lighting. Live Epstein is lit from above whereas dead Epstein is effectively lit from below and straight on.
They should have propped him up a little and put a party hat on him. With noisemaker.
