iCloud photo storage size vs downloaded 'icloud photos' size
iCloud is reporting I have used 34Gb for the storage of near 4500 photos, though if I download them via the web interface (in 5 files "iCloud Photos.zip" files (a 1000 at a time) to my PC, the total of the 5 extracted downloads totals 9.3Gb, which also is what my iphone (8plus 256Gb) shows - optimization is turned off.
Under media types 1 video (2.8mb), 18 live photos and 30 screen shots are listed.
Somewhat confused as to the near 400% difference, anyone any idea why this might be the case?
many thanks in advance.
