No that does not appear to be related.

The ipdf inserted PDF images do not pass through that code, they are never SVM.
Rather the deletion/restore of the pdfium generated bitmap (PNG) breaks its
linkage to its source PDF. That facet is fixed somewhere already in the filter
implementation/image management for 6.1 and master/6.2,
