Allen being plugged into the recorder still doesn't mean he learned absolutely everything, and, FYI, he was on Evillious for pretty much all of Gallerian's life so he wasn't making sure Allen was learning the entire time. And learning about Gallerian, again, doesn't mean that he learned specifically that Gallerian contracted with the Demon of Greed. It's possible that the box had incorrect information for whatever reason. He is still in a biased position because he did not witness Gallerian's contract and only knows about it from a secondary source.

It's also possible that the translation is the problem, such as, for example, things Allen said with certainty in the translation were really intended to be uncertain. "He's the one who apparently contracted with the Demon of Greed", etc. It could explain some of the other oddities you're talking about.

All of my points still stand--just because an in-universe explanation for the inconsistency is unlikely doesn't mean that one is impossible. You have repeatedly used the phrase, "we can assume"--if you're making an assumption, it is not strictly confirmed. If we begin with the premise that Allen was misinformed then we CAN'T assume he learned everything until the world's end.

So in short, no I don't think we should make a trivia about it any more than we should make a trivia point stating "previous material stated Kayo killed out of insanity but the book reveals she killed to get revenge on Kai".
