Isn't that photo specific backup rather than general backups? Last I tried, Dropbox on iPhone cannot backup any files owned by other apps automatically. You'd have to export it manually to Dropbox.
Edit; It looks like this is possible on iOS for apps to access other app's file sandboxes with a somewhat recent iOS update. MobiusSync (Syncthing client for iOS) has beta support for it. But I see no mention of Dropbox adding support for anything similar
It’s true that I have some app data being stored in iCloud, but it is VERY within the free tier space limit. But depends on the app, many apps support Dropbox themselves and I store the data in Dropbox for those.
