There wont be alot of dc on mains since your 240V comes off a transformer in a substation which is usually pretty close in towns and up a pole in the country. I'd agree with the probability of maybe harmonic distortion from goodness-knows what reactive loads at some point. ISTR a good example in the past was half wave rectified heater chains, though we've generally moved on!?
