Given that the images of the house were taken over two months apart (look
at the EXIF information on the JPEGs), how can one expect the colours to
be the same? Actually, there's some critical point I'm missing here -
given that the images were taken two months apart, how can the angle of
the sun be exactly the same? These aren't images of real objects, but
images of other images! No way can you compare the colour rendition
unless you are buying a camera to photograph other photographs.

Yes, the house images are photographs of photographs. But that doesn't
invalidate the comparison: the camera has no way of telling that the
photons it sees are reflected from paper rather than real
grass/trees/house.
