I am not a fiber expert. So my opinion might not mean much,but, first,other than what appears to be the same color and the fact they are fiber shaped, I see nothing similar about them.
Second, if you notice the background in each is a different color, that means that the colors of the fibers are actually different. If the picture is corrected to make the backgrouds come out the same, then the fibers will be different.
If it is because the backgrounds actually were a different color, then that throws the whole comparison ability out the window.
