I don't think WB has the events that BitmapImage does to wait for it to open. I would try using BitmapDecoder/CreateAsync/GetPixelDataAsync/DetachPixelData and copy resulting byte array to the WB's pixel buffer instead of calling wb.SetSource(). Then maybe call wb.Invalidate(). Or maybe just replace the Delay call with an Invalidate one.
