How Gmail’s Image Caching Affects Open Tracking
ok makes sense. a file hash might fix that and save google some bandwidth but i imagine they do not want to break tracking completely for now...

To hash the file you first have to download it. Downloading it is the tracking action, not showing it. Deduplication does not affect open tracking pixels.
