Your question is too complicated because you can have digital prints printed out (in an admittedly digital way) to analog media like c-prints and you can have analog media scanned into a digital form and displayed on a digital display. You just say "images" without specifying what you would actually be looking at. Often when people ask these questions they are talking about the differences between a digital image that originates in a digital camera directly capturing an image from a lens, versus a digital image that originates by capturing a piece of film or something. But those two things are both digital images, and not really a comparison between analog and digital images.

A computer monitor is the lowest common denominator. If you are looking at two digital images on a computer monitor, one of which happens to originate from a scanned artifact, you are still comparing two digital images. Actual color slides and maybe prints can contain colors and dynamic ranges that cannot be displayed on a computer monitor. This is clearly seen if you shoot some well-exposed slides of flowers or other colorful objects. You will see browns and purples and white-to-black ranges that you will never see on a computer monitor.
