It could just be the flash but they do look very wet, just to be sure, none of the eggs are in any direct contact with any water, right? BP eggs should be exposed to as much humidity as possible with no direct contact with liquid water.
I would try to separate the 2 middle eggs from the other as much as possible.
And let me ask you this, on the discolored eggs that have veins, how well do the veins look?
In a healthy BP egg the veins look nice and defined. On dead eggs they tend to start looking blurry and frayed as the veins start to break down.
