The absolute voltage levels do not matter for digital signals but the slopes between 0 and 1 votage levels matter as the 1 phase is longer at slow slope rates compared to fast ones at the threshold voltage. That plays a role if the timing = jitter is important like with SPDIF or AES. Not so much with USB or ethernet but still they can also transmit noise independent from the digital data stream.
The problem with cables is that there is little correlation between price and performance.
