I think we are all talking about a really strong yellow cast. It looks somewhat like daylight film used under tungsten lighting, or photos shot on daylight film in daylight but through a deep yellow or tobacco filter. When this yellow cast is not present, the Aviphot films from Maco or Wittner show just a little yellow, as you say.

I have this yellow on rolls that have fogged sprocket holes on their first few frames, but also on rolls that do not have any fogging along the sprocket holes.

The Maco website now has a strongly worded warning about the risk of light piping on polyester films.
