Question: "Snowflake" XMB shader pipeline

For quite a long time, I’ve wondered what does the “Snowflake” option does, as a menu shader pipeline in the XMB interface. For me, it does nothing, even across different devices; it’s the same as if the shader pipeline was disabled. All the other options show a visual effect, except this one. Is “Snowflake” glitched or is it intended for a particular use?
