The feature wall was requested to be the focal point and stop the end of the room being a dead zone. With dining rooms there is often a feeling of needing to fill the walls or space just to make it look more useable and full. With using a paper with a reflection you don't take away any space but add to the image that there is more content in the room than there actually is. This still gives the room an airy feel, without it being cluttered or overly dominating.
