Zavvi and other sites have the listing as a Sony Release
There is also a Terminator 1-4 Box Set which is also listed as a Sony release
So I'm not sure if this is from StudioCanal
This means the Blu-ray Disc is unknown as to what version we are getting
If this was a StudioCanal release there would be a title on the spine as recent Big Blue the mock artwork had no title on the spine but the steelbook did have
It is a Tri Star Film which is Sony but previous distribution for the UK was through StudioCanal
So its unknown 100% until actual release if this is a Sony or StudioCanal release
