Keep in mind that PFG-03 may not be a 100% reliable source for Lippmann photos. Perhaps there was/is too much fluctuation from one batch to another.
As for the processing, some rehalogenating bleaches may actually damage the integrity of the recorded “Lippmann fringes“. So using a colloidal developer like GP-2 or alike seems to be a better approach. Since that method doesn't involve any bleaching, the finished layer will show both amplitude and phase characteristics.
