Both appear to be True Green PE. The upper one looks like it was kept in very high lighting, hence the speckling on the oral disc. High light will have to be maintained in order to retain the speckles on new polyps. Since they are recent acquisitions, it will be interesting to see what happens to the coloration over the long run in the same system. I had a couple different color morphs of the TGPE, and they retained their respective color differences for well over a year in the same system.
Here's a link to a article on speckling as a result of lighting;
