I received 2 or 3 D. regias and a few P. launea's, a few days ago. The pings were all green on arrival and still are. The sundews were mostly green, with a some black and brown. I got the package minutes after it was delivered, right before heading to work. So I took a few minutes to unpack and pot up. Never would have thought to rinse any of the agar and decided against keeping them in the bags. So I just set them open tray, in the LFS that they came in, but with indirect lighting to start them out. As far as I can tell, they weren't set back at all. I see one emergent leaf from a regia crown and it is still turgid to the touch. In other words, I think it is alive and growing. One existent leaf might actually have dew on it.
Thanks, Travis!
