Shipping build removing nearest neighbour texture settings

I am making a game that has a pixelated texture look. To achieve this, when I import a texture, I right click on it and Sprite Actions > Apply Paper2D Texture Settings. Which to my knowledge just enables transparency and nearest neighbour.

In editor, and in a development build, this works perfectly without issue. Some textures are not changed, like noise masks or UI textures for example.

However when I package a shipping build, all textures appear to revert to normal textures, without the nearest neighbour and other settings set. I don’t have much set in the packaging settings other than Cook Only Maps which is set to True.

Has anyone encountered this before? It’s sort of integral to the style of the game so I have to find a fix for it.
