Hung side by side, these appear as different sheens, depending on room lighting. For commercial goods, this is easily solved by cutting or tearing off the offending side a few inches. On residential papers, your client is the judge of acceptability. In a perfect world, embossing would be completely even. That's not going to change, so you'd better develop techniques for dealing with it.
Modern materials can be wipeable, washable, scrubbable, peelable, and strippable.
In making these advances, compromises are made. With the introduction of vinyl, shading became a problem. With commercial materials, this was easily solved by reversing the material. Only under extreme lighting conditions, such as wall washers, would shading or embossing depth be visible. However, on patterned non-random residential materials, shading can be prominent.
