How should a deep-space photograph be classified regarding its accuracy to reality?

As a scientific map of data rather than a traditional photograph.

Deep-space photography is fundamentally different from traditional landscape or portrait photography. Because the universe is dark and objects are faint, these images are constructed through long-exposure techniques, data integration, and often the application of false color mapping to visualize invisible chemical compositions. Consequently, these images are not simple captures of a scene but are sophisticated scientific maps. They represent data that no single human eye could ever perceive simultaneously, functioning as a tool for interpreting the physical reality of the universe rather than a direct visual record of how a human would experience the scene.
