I checked for libtorrent documentation. As I suspected, qBittorrent displayed the total amounts uploaded / downloaded (Payload + protocol overhead). Trackers only display the payload amount.
Unfortunately, libtorrent does not seems to report the all_time_payload_upload / upload, only all_time_download / upload.
I will probably file a feature request against libtorrent but I least you know the reason now.
libtorrent *does* report the amounts correctly to the trackers.
