Dev-Prod Configs from Pak file

Gives you an idea of more settings you can edit in %LOCALAPPDATA%\Sifu\Saved\Config\WindowsNoEditor\

like disable Motionblur, AO, Fog, VolumetricFog, Bloom, LensFlare, DoF, FOV etc.

Engine folder is most likely Dev and Sifu is most likely Prod as it matches up more with default settings (i.e. skip videos and a few more settings)

Would also recommend using UUUnlocker  so you can get the console and can manually set the settings to see what they do.  Might need to do some guessing as it wont show all of them but you can see some of them by typing Show

From there you can do FOV 110 to set the FOV, or r.fog 0 to disable fog
