I should have mention there is an article in how to spot such spots on Venus. This might be useful if someone might want to try to see it for themselves.

Sadly, Venus with its "open phase" 74% and increasing would mean it would be difficult to see along the marginal visual terminator. However the morning easterly elongation is about 40 degrees from the sun, and worst is the disk is merely 14 arcsec and also decreasing. Even observations in daylight of any surface features would be presently as difficult.
