To give you an example of the discrepancy the 'Helsinki Wallpaper' is shown as 21.8MB (if I click on 'details' just before download it also says 'Download size: 21.8MB) Yet when I actually do download it the progress bar shows it's actual size is only 3.42MB, which makes sense for what is basically 4 jpgs. All the apps are showing basically the same download size, give or take a MB or so. Looks like it's only me with this issue and a reflash would solve it, but I can live with it for now.
