The Blu-ray I own is the 2015 Code Red one, which is listed on Blu-ray.com here:

Apart from the different cover art work, the 2015 release also has different disc content. I believe the movie is the same (the runtime is the same at least), and it includes the "Katarina's Nightmare Theater Bucketlist Mode", but does not include any other extras (i.e. it has no Theatrical Trailer and no bonus trailers). So the 2015 release should probably be given its own separate entry in the list, and its mention in the Notes section of the 2021 entry should be changed or removed.
Note: Having finally got round to watching the Blu-ray, I was originally going to send a message regarding the status of the gore shot, but it seems Eric has already corrected the Blu-ray and DVD pages regarding this. I don't know why in an earlier thread I thought that Dimension Pictures didn't exist at the time the movie was made - it seems it DID exist. Maybe I was confusing it with Dimension Films, a different company found in 1992.
