WebCamTexture Quality Not Good

Hello, I am working on a unity project in which I am using Logitech 4K webcam to show live feed using webcamtexture, and then capture the image of a live feed camera by clicking the button. But the camera quality is not good on webcamtexture, but the camera I am using is of good quality, I want that quality in my unity project, can anyone help me in this, that how we can achieve good camera quality using webcamtexture. Thank you. :)
