Webcam whitebalance range

[Shad0wman37]

Hi, I've recently bought a wansview 105 Webcam, and I was trying to adjust the whitebalance settings. I use lightspectrum Evo on my phone to get an idea of the value, which is usually in the 4000-5000 range (the Webcam is facing a window) but the whitebalance range only goes from 300(warm)-600(cool). Is there some setting im missing?
