PFM crown showing grey line from day 1, is it because dentist didn't push it up far enough?

Hi had a PFM crown put in for molar. dentist said best to use a PFM as it is slightly stronger but in time, I MAY get a grey line around the gum line as the gum recedes. However as soon as he put it in I saw a very clear grey line and obviously that is not due to receding gum. He says it is not the metal showing but rather the color difference between my tooth and the crown. But the crown actually matches it very well. So is it because he didn’t push It far up in enough ?
