Should a backsplash go to the ceiling or stop at the upper cabinets?

Standard is to fill the gap between the countertop and the upper cabinets, usually around 450mm. Running to the ceiling works where there is a range hood with open wall on either side, or a window wall with no uppers, and it makes a small kitchen feel taller. What rarely works is stopping partway up a wall with no cabinet above it, because the edge has nothing to resolve against and the eye goes straight to it.
