I was wondering if this installation looks normal (see pictures). One of the reasons that we have asked for the quartz countertop was that we thought that the seam wouldn't be that obvious. But the thing that we have got looks very obvious to us. So I was wondering if my expectations was unrealistically high or this is actually an unprofessional work. Also, it seems that the part underneath is not sealed properly (please see the last pic). I was wondering if this is normal practice. The first picture is the seam, the second is the view from the side, and the last one is the view from under.
