No, not at all. I don't read a book to regurgitate the text in an imperfect form later. I read it to learn about the ideas and thought. The syntax itself (ie. text) is not that important.

So, you're preferentially discarding information you consider extraneous to your application, distilling it to a smaller representation that retains what you consider important about it.
Most image compression smooths skies. Because most people don’t want a regurgitated sky. If you’re an astronomer, on the other hand, you’ll compress away the trees. These are all lossy retrieval (and, inherent to compression, transformation) functions.
