Is there an advantage to optimizing a PDF using pdftron.PDF.Optimizer before converting to ePub

Is there an advantage to optimizing a PDF using pdftron.PDF.Optimizer and pdftron.PDF.Flattener before converting to ePub. Thinking that optimizing images and simplifying the PDF would result in a simpler / smaller ePub.

There is no point in using Optimizer or Flattener when prior to export to EPUB because this conversion implicitly involves Flattening.
