Different HDMI cables will not improve the picture quality as it is a digital signal. But higher HDMI versions, i.e. HDMI 2.1 cable will provide more bandwidth for 4K 60Hz, an earlier version may still display 4K but have graphics artefacts. So if you are having issues with the picture showing random pixels or the image freezing etc get an higher model HDMI cable. But it will not improve stream quality. See the many other posts here to improve that.
