COBE determined that the background radiation is indeed NOT uniform,

but
rather blotchy. Even though that difference is measured in fractions

of
a
degree K, nonetheless it matches the "clumpiness" of galaxy cluster
distribution throughout the observable universe.


Maybe you should revisit the figures. What's the magnitude
of the "blotchiness"? I think you'll find that the background
is remarkably uniform, and that the deviations are very, very
tiny in temperature.

The pictures there are lacking a legible measurement
scale that would allow their interpretation as to
actual variation magnitude.

Take a look here instead:

Here's a brief quote:

"There were variations in signal from the early
Universe at a level of one part in 100,000."

That's pretty small.
