I just tried this while not having sqlite3 installed.

This works:

NIX_AUTO_RUN=1 gphoto2

This does not:

NIX_AUTO_RUN=1 sqlite3

Perhaps this feature only works when the package name is equal to the 
executable name. Or the issue is that there are two packages with the same 
executable name.

sqlite> select * from programs where name = 'sqlite3';
sqlite3|i686-linux|sqlite
sqlite3|i686-linux|sqlite-interactive
sqlite3|x86_64-linux|sqlite
sqlite3|x86_64-linux|sqlite-interactive

sqlite> select * from programs where name = 'gphoto2';
gphoto2|i686-linux|gphoto2
gphoto2|x86_64-linux|gphoto2

Cheers,
Jos
