Well, the shops have all this split-screen stuff, with one side in SD 
and the other side in HD. The only difference I can see is that the HD 
is very slightly less blurry. But it's a tiny difference - certainly not 
worth paying £20,000 for.

...there's a difference between them?

Meaning no blur *if* the signal is uncompressed - which it never ever 
will be.

In reality, we just swapped analogue distortion for compression 
artifacts. (And - if you're talking about transmission - a different 
failure mode in case of interference. Although admittedly it takes more 
interference now to make it fail.)
