Potential Spoilers - Unused Assets

I've finished all known puzzles at this time and like everyone else feel like there must be more. I kept a OneNote where I was tracking unused hints and clues and have a section dedicated to pictures of (presumably) Mary. There are multiple pictures of Mary in the house where she slowly accumulates more jewelery as she ages. The jewelery not being subtle at all either, as it is the only part of the image with color. My thought being that the rooms, when assembled in some way, would give a hint/clue, but I'm coming up empty. I didn't see much discussion anywhere about this and was curious what others thought. My initial thought was maybe the 8 realms puzzle, with each piece of jewlery color corresponding to a region and the order of acquisition being the peg order.
