Bear in mind that the differences from homogeneity and isotropy exist on
scales. The statement that our universe is homogeneous and isotropic is a statistical statement, which is another way of saying it's an approximation.
But just fyi, once you remove the dipole of the CMB (which is mostly due to our motion), the CMB is uniform to about one part in 100,000.
Ok I see what you are saying.
Thanks for the information Chalnoth.
