The third link does work, but it is only a collection of about 50 photos of Venus from the University. So it's no big deal.
Venus should always be white, or at least almost white(perhaps beige-like) in off years. It's likely that your original source either sent you the wrong plant, or they sent you a seedling of the true Venus, thinking the seedling would look like the mother, which they never would. (The seedlings would not come true.) The real Venus is only propagated through asexual means, like cuttings. Never seeds.
The most likely scenario, I think, is that you received the wrong plant.
