Bud, Should have been scribed. Or, new back splash should have been supplied/installed. In the event a new back splash were installed, the gap "could" be compensated for with wall float, such as CustomFloat. It might show a slightly wide grout line on the ends but that's far less of an eyesore than what is there now.
