Normalize on CBZ conversion changes white pages to black pages

Bug Description

When I convert a CBZ with full white pages without "don't normalize" option checked, the full white pages are converted to black pages.

I understand the concept of improving contrast etc, but maybe it should not be activated for full white ?

Example of source and output files are attached

Other information:
- Calibre 5.25 64 bits
- Windows 10
