UK Da Vinci Code Blu is the extended cut only, with no BBFC cuts.
UK Angels & Demons Blu has both the US theatrical cut and the extended cut, with no BBFC cuts to either cut.
The UK Da Vinci Code/Angels & Demons double film set on Blu is missing the second (extras) disc from the standalone UK Da Vinci Code Blu release as far as I'm aware. Da Vinci Code movie disc in double film set is the exact same disc as disc one of the standalone release as far as I'm aware.
Hope that helps.
