What is the difference between the US / EU "The Evil Within" and the Japanese version when the Gore DLC has been applied?

The Evil Within is called Psychobreak inside Japan. In Japan, the game's graphic violence is actually turned down, disabling features such as dismemberment and full body explosions.

There is a Gore DLC however

What this does is enable these graphic features, which makes the graphic intensity the same as the Western Versions. There is NO dumbing down in both the US/EU versions.

The reason was that if they released the game without dumbing it down, it would have the rating of "CERO-Z", which is the maximum rating inside Japan. To allow a broaden market, they dumbed the intensity so that it would fit the "CERO-D rating, which is the maximum rating that allows people to play under the ages of 17. Those above 18 were given a DLC code to activate the gore.

Here are some comparisons:

The game with the Gore DLC/US & EU versions. Noticed the increase gore, blood and dimemberement.

Here is another comparison

Here is an enemy with a hit on the head. This is from the Vanilla Japan Version
Now look at the same instance with the DLC Activate/US& EU version. Noticed the blood affects, and the dismembered head
