It’s more so about scale. If you zoomed out far enough the CMBR is homogeneous. You can zoom in to about anything and it’ll not be homogeneous.

This map is covers the entire observable universe, it’s as zoomed out as it can go and it looks pretty rough in patches.
Edit: Oh, unless by zoomed out you mean beyond the observable
Zephyr@sh.itjust.works 3 weeks ago
Yup, the observable universe shouldn’t be anything special necessarily. That is the universe should to on beyond it.

But the only assumptions we can make about the unobserved universe comes from particle/quantum physics, which we explore in an idealised form
