Poor quality, poor craftmanship, poor quality of materials.
Every touch of "nap" causes a mark until you back brush, then it does not look like it's dirty.
There are warp and weft directions to fabrics.  Warp is horizontal, weft the length of finished fabric.  It's wrong, any movement on cushions or any piece of fabric show dark prints.
That includes cat paw marks.  Back rub to remove apparent dirt look.  Too much work
