You are correct in stating the proviso "as long as it is to spec." The issue is that Premium Certified cables are verified through industry-established testing standards to meet the HDMI 2.0b specifications for 4K/UHD signals. It is that reassurance that makes them a preferable choice for many of us who value a reliable connection for high-quality video, especially given that these cables are available at very low prices from trusted sources such as Monoprice.
