Notebook Video, Display and Touch

 i just bought a brand new HP Envy x360 15-ee0xxx , and am dismayed to find  that the webcam quality is awful. Porous, grainy,  with huge pixels (if that's the right word) very poor definition, coarse and oddly colored.

I was intending to use it to Zoom this winter, I have been using a webcam on my PC, which is fine, but confined to a small office not lit well enough for Zooming on dark days. I have an Ipad from probably 2011 I have used and a Chromebook, also older, all of which have far far better webcams.. clear, good color, sharp pictures. I am pleased to see that I can finally get a virtual background on this device, but the picture quality is horrible.  Is this a fault of all HP laptops, or just all Envy x 360s or just a defect unique to this particular device?    We chose it after looking at reviews over other models, other mfrs... but I don't recall any reviewer shouting out about the horrid webcam quality. Surely at this point in time, one of the more important qualities a laptop must have is a finely functioning webcam.  

Has anyone had the same experiences, or is this a defect of just this one computer, and if so, something that can be adjusted or is it just a lemon?
