White case Kobo Libra Colour screen dark line at top

Many people with white cased Kobo Libra Colours are reporting a solid line visible at the top of their screen. Can this be from a misaligned screen? I was trying to see from the replacment instructions is their room to slight shift the alignment upwards?
