That's my entire industry, so I can believe it. I'd love to learn large scale game architecture but it simply isn't public. At best you can dig into the source available 30 year legacy code of Unreal Engine as a base. But extracting architecture from the source is like looking at a building without a schematic.

Your best bet is a 500 dollar GDC vault that offers relative scraps of a schematic and making your own from those experiences.

Have you seen the presentation from GDC 2017 on the architecture of Overwatch [0]? If you watch the video in detail -- stepping through frame-by-frame at some points -- it provides a nearly complete schematic of the game's architecture. That's probably why the video has since been made unlisted.
