Your post mentions and Inspiron Laptop, yet the service tag number that you provided shows as a Latitude 7400? Please check the service tag number again.  
My Inspiron laptop (with Windows 10) webcam has strange colors - everything always comes out looking purple. Yet despite wasting lots of time poking around, I can't seem to find anyway to adjust the color setting to make the colors look more natural. Any thoughts on how to adjust the way my webcam video color comes out?
