EDIT: As pointed out by @NightmareT12, there are parts of Nidus' abilities that use assets created after Warframe started using PBR (like his Larva) but they are mixed in with assets that were reused from the Infested Corpus Ship tileset which was released before PBR was added. I have made changes in the post to reflect this information. I'm very happy that the issue of energy colors not properly applying to Nidus' Ravenous tendrils was fixed, but unfortunately his Infestation still remains
