I just did a take-out today based on your comment here.
I received links to over 100 tgz files (4GB each), and checked a couple. Each had JPG files and JSON files with extra metadata ("geoDataExif", "geoData" (inferred from my location history?), "title", "description", etc).
I can't tell if the actual images are the originals I uploaded, but I can confirm the images were archived as actual images, and in a serviceable format/structure.
