This is the impression I got from everything I saw in the newer story for non-Legacy characters; I may be biased though, because I personally have CPTSD and I know plenty of soldiers and victims of war who have PTSD.
The whole "Foggy Memory Syndrome" actually struck me as being more like war-time PTSD, where the memories of the events become blurred and fragmented because the mind can't handle everything it witnessed.
I go the impression that the bulk of the NPCs (up through level 15 or so) who ever talk about the memory issues surrounding the Calamity weren't directly at the battle, or at least weren't close enough to see all of it. They likely saw Bahamut break free from his prison, and the attempt to imprison him again, and then saw something happen on the field, but had no idea what happened - even if they could see Louisoix do something just before-hand.
With how many people were time-skipped, there would be no way for even battlefield observers to keep track of who disappeared due to being burned alive and who just vanished, or who ran away and laid low, or what not. Distant observers would have even a harder time, and those who weren't there at all wouldn't have any way of clearly knowing what happened.
So we end up with people probably knowing who all went to the battle, but not knowing who all died in the Primal's fires, or who all were affected by some sort of magic no one understood (time magic seems sort of like a higher level of magic than most people deal with) and even what that magic did, or where everyone went after the battle.
Those who were battlefield observers or nearby observers would have seen some people enveloped in intense light, obscuring who they were; while they didn't know what that light did to them, it created a strong imagery of heroes who did something to fight against the Calamity. Hence the whole "Warriors of Light" whom people really can't recall as anything but silhouettes; eventually, the stories would propagate enough that even people who weren't there would have a very strong idea of that imagery.
As time passes, the memory suppression effects of PTSD can get worse. For those who were not time-skipped, it's been five years at minimum since they've seen any of the Legacy characters who got time skipped. Those like the Grand Company leaders, super well known individuals from the main story, etc. are more likely to be remembered faster than those who were not as well known. If there's not enough contact with the lesser known time-skippers or time-skippers an NPC hadn't seen for sometime before the Calamity, their likely to not be able to connect the dots before the person leaves.
These people who were left behind also had to deal with the whole rebuilding of life for the past five years, and had to focus on other things aside from their lost loved ones and lost protectors. That's going to play a part in how well people remember what happened; a lot may have accepted that something horrible happened, and rather than dwell on it, they focused on rebuilding and stabilization.
There's also the fact that it may be hard for someone who didn't get time skipped to believe that a time skipper is actually who they believe they are; for example, I had a friend that moved away immediately after high school, I was told she had died, and years later when she returned to the area, I initially couldn't believe it was actually her. Sure, in that case, the person aged but once someone believes that another person is dead or not coming back...it's hard to deal with it when they do.
Overall, that's the impressions I got about the situation. Rationally, it makes more sense than just "everyone has mass amnesia", and provides for varying degrees of amnesia and acceptance of the time skippers.
