Friday the 13th (2009) - UK release vs US release

[Funktion]

The recent remake of Friday the 13th was released on BD by Warner Bros. in the United States, but Paramount is handling it's release in Europe.
While the US release includes 2 cuts of the film, only the longer cut is mentioned on the press release for Paramount's disc.

Some stores are already shipping the UK release of the film, and I was wondering if anyone already checked it out, and could confirm:
-if the theatrical cut is also included on the disc?
-if there are any improvements regarding the US disc? The Region A Blu-Ray had 2 cuts of the film on a single disc, and they were apparently different encodes (not branching). If the UK disc only includes one of the cuts, they either improved the bitrate a bit, or maybe they simply turned it into a single layer disc (hopefully that's not the case)?

Additionally, does anyone know if the differences between the 2 cuts are mere extensions to existing scenes (making the theatrical cut's inclusion more or less redundant), or do these cuts feature different takes/alternate scenes/...?
