You can listen to the DataGrid.PreparingCellForEdit event (or maybe DataGrid.BeginningEdit but I'm not 100% positive) and store the cell's value at that point.

Then instead of listening to DataGrid.CellEditEnded, listen instead to DataGrid.CellEditEnding. This event is specifically designed to give you an option to cancel the editing so it's not treated as a commit. The DataGridCellEditEndingEventArgs for it provides a Cancel bool property. Check if the new value is the same as the old value, and if it is, set the the Cancel property to true. Then when the CellEditEnded event fires, its EditAction will be Cancel.

void MyGrid_PreparingCellForEdit(object sender, DataGridPreparingCellForEditEventArgs args)
{
    //store current value
}

void MyGrid_CellEditEnding(object sender, DataGridCellEditEndingEventArgs args)
{
    //check if values are the same
    if (valuesAreSame)
        args.Cancel = true;
}
