Updated the OP with the game update news 
An update seems to have started rolling out, players in Korea are allegedly able to download version 3.6. The update appears to be as significant as was hinted at. Saves now have compatibility with the PC version, meaning you can progress through the Switch edition and continue on where you left off on Steam (and supposedly GOG) and vice versa. Additionally, it looks like several graphics options can be tinkered with.
Based on the reddit post, there are eight new graphic FX options available:
Motion blur
Blur effect
* Bloom
* Sharpen
* Depth of Field
* Depth of Field for Cut-scenes
* Chromatic Aberration
* Water Quality
* Foliage Visibility Range
* Anti-Aliasing
And following are two screenshots comparing Sharpen OFF vs MAX.
