Nothing.
Notes
The default "alphamultiply" alpha mode should normally be preferred except when drawing content with pre-multiplied alpha. If content is drawn to a Canvas using the "alphamultiply" mode, the Canvas texture will have pre-multiplied alpha afterwards, so the "premultiplied" alpha mode should generally be used when drawing a Canvas to the screen.
