Depth effect on Lock Screen is inconsistent

[unobtainium]

For some reason the 12 is not behind the mountains on the horizon while the 10 is. Can anyone figure out why the Depth Effect would be inconsistent like this? Are others seeing the same issue?

It's using AI to detect the foreground and background. It's not going to always be perfect. To me, it looks like the 12 is behind the mountains. I can also see the bottom parts of the 10 if I look closely.
