The problem is, in my opinion, she's never capitalised on what sets her apart from other YouTubers. She's old and stale now.
Dubai was a nail in her coffin - it's not that she went away, it was the lying to her followers. Well before that she should have been transitioning away from beauty and in to her home, luxury travel, etc.
Her decor is hit and miss in my eyes but she could easily get 3-4 videos out of one room; over-view of room and plans, come to an auction with me, redecorating vlog and final reveal with what worked and didn't. She could even go in to her budget (which I know is personal but would be interesting) and then compare for similar items at lower price points.
The garden is massive, I know she has a gardener but she could easily do cooking videos where they only eat what they've grown once a month or something.
She has rooms I could never dream of owning. A genuine review of a cinema room, boot room, home gym and how essential they are and how often they genuinely get used etc.
The ideas are endless but she's stuck in the same mindset she always has been - it's the same reason her style has never evolved, she will never cut her hair and her videos are the same cut and paste.
