There’s quite a range (haha bad pun)of shades in the grau and falb fees. It depends on a lot of factors, was the range pattern bird Rosetta or Tibetan, do they have 1 or 2 copies of fee. A bird with one copy of fee can end up looking very black/gray or it can have a lot of beige and creams mixed in. The double fees will be the most dark and black/gray with nearly no brown tones at all. Probably a lot of the photos you see are people showing off their lines, and they will often post the sharpest double fees.
