Nope. There is no data to back that up.
Audio cables are an analog signal, this means signal integrity matters more as it has a direct impact on sound quality. We use gold conctact on things because it prevents corrosion and has lower resistance. On a HDMI cable it won't impact quality at all (it's digital) but might reduce corrosion enough to increase the life of the cable.
