When Schneider bought up the remains of Goerz, they made the lenses as the APO-Artar until the mid-1990s.
It's possible that Schneider used more modern coatings on the later lenses, so you might see a contrast increase with their versions; but I'd guess that you'd be hard-pressed to see a difference without some rigorous testing. Those Red Dot Artars are excellent lenses. For many years I used a 1950s model on the job; it was sharper than any use we could put it to.
