Yes, as long as the cable actually carries the signal. If there's too much interference or other problems with the cable, the SNR will drop to the point where error-correction can't obtain the original information, and you'll get a blank screen. The HDMI specs ensure that the cable meets the minimum to carry enough of the information so it can be reconstructed. Obviously, anything beyond this is just marketing crap. The second category ensures a higher spec as SNR is likely to be lower at a higher clock speed (340Mhz), which is needed for 1080p60 and other high-bandwidth needs.
But in practice, the cables are usually decently made enough for both categories of HDMI signal, hence the "buy the cheapest one" advice.
