Of the minor but noticable changes:

• Bottom icons and text are bigger for some reason on Apple mode. Maybe more readable?
• Share icon is the "network dots" on Android, but the weird "up-arrow page" icon on Apple. Honestly I've never liked that Apple icon, hated Safari cause that icon doesn't scream "share" to me.

Biggest issue for me? Why the hell does Android mode throw a grey bar at the top unlike the all pitch-black that Apple mode has. It looks clean and smooth on that mode and jarring and ugly on Android mode 😮‍💨

Edit: So I figured it out, if you have "pure black dark" mode enabled, it will apply that to the bars on Apple mode, but not Android mode. Top bar also doesn't follow the app color scheme, it's white no matter what, unlike the blue in Apple mode.
