I've 100% the game, and you must do it, because you unlock a pretty interesting (and really unexpected and surprising, at least for me) bit of information, that I came here to comment XD.
The 2d memory was precisely what caught me off guard. I'm not sure what we're supposed to see, but it's that a rebel Chozo faction or what? Or maybe another race which came to help the Chozo in the SR388 planet with the Metroid menace and afterwards they rebel agains the Chozo? I thought the Chozo were all good guys, and this illustration was dope because of that. This was pretty interesting, and I can't wait to see how this is going to develop in the next games. Also, that 2D/10 text... Are they hinting to a new Metroid 2D game revolving around that villain? HYPE!
