Another good way to see how little is in U and V is to split the image
up as you have done, and then blur one of the planes, and then
recombine them into a single image. Blurring the U and V planes has very
little effect compared to blurring the Y plane by the same amount.

Another fun demonstration is to combine the Y plane from one image with
the U and V planes from an unrelated image. The result looks much more
like the Y image.

There are lots of other sets of data you can do the same sort of demos
on, for example: the phase of the Fourier transform of an image conveys
much more information than the amplitude.
