I copied your provided overlays folder to /data folder, and installed the theme fine, but it doesn't appear in Theme section.
Oh yeah me too like this (theme doesn't appeae in theme section)
1. Open data/overlays/jsonfiles/userjson
Delete this --> com.samsung.Batmantheme.json
2. Try open lucky patcher/titanium backup
For look apk's from theme installed or not
If installed (example like com.batman.blabla) uninstall it all via lucky/titanium
2. If not installed
Reboot your device reinstall the theme
Wait minute until a pop-up installed completed
(i recomended you do not use your device when an installation wait minute)
