Is there a way to report pages that have never been visited ?

With a goal of trying to report on the absence of data, where even a single page view would move the page in question from the "no traffic" column to the "has traffic" column, your best bet is probably to do your analysis outside of Analytics.

With that, as long as you have a complete list of pages to compare against, you could possibly build a solution using Adobe's Excel plugin (Report Builder). This should be dynamic enough, with the ability to quickly update date ranges, metrics, and the list of known pages for your lookup (vlookup).
