Downloaded PPTX from Google Slides for archiving

Open the following link in Google Slides, then download it in PPTX format: https://docs.google.com/presentation/d/1P5gHa4cC6CjSQez0i6ua3c44IcwuxI2bNxI2qgCJTAY/edit?usp=sharing

In the template (master) of the very first slide you can see that the main "pictogram image" has 50% transparency applied. Same as in Office 2013 if you open the downloaded file there.

If you download and open it in Impress, opacity, contrast and brightness of the image are all set to 0%.
