What are the differences between the 2004 and 2015 releases?

The evidence I have only lists films that have been released in IMAX and discusses the use of IMAX Digital Media Remastering and 70mm prints. It does not reference any specific title that had releases in both 2004 and 2015, nor does it provide details about changes in format, content, or presentation between those years. Because of this lack of data, I cannot accurately compare the two releases. If you can provide the name of the film or additional contextual information, I would be happy to offer a precise comparison.
