PDF export colour profile different to MSOffice export?

[postenterprise]

Starting from the very same source docx (export from google docs), the PDF exports from LibreOffice and MSOffice (both latest stable versions) gives images with different colours.

Why is this? Can it be fixed?

Is Libreoffice ignoring or stripping out the colour profile of the images? is it MS Office 2016 for Mac that is doing this wrong?

2 examples attached showing clearly the different colours.

Can you supply the original images for testing?
And the original ODT or DOCX files.
And PDFs?
I would look at the color profile in the orginal images and then compare to the images extracted from the subsequent files.
