Good news and bad news. The good news is that I was in John Lewis on Thursday, and they had the television, full model number Sony KD55X9005ABU 55" 4K LED, cost £4K. I was more impressed with this 55" version than I had been with the 65" version in the Sony store. In John Lewis, they were showing mainly demonstration 4K material, which I must say did look very good on the 55" screen. I got home and played the demonstation montage material from my Spears and Munsil Blu-Ray test disc on both my 64" Samsung in the parlour and the 60" LG in the kitchen, and I'm happy
to concede that probably the 4K material, on the 55" Sony in John Lewis, did look a bit better (though not overwhelminghly better) than the Spears and Munsil disc as shown on my large televisions. (Why I hadn't been as impressed with the 65" 4K Sony in the Sony shop about a week ago, I'm not sure, although I did not see the same 4K material on both the Sony screens, maybe the John Lewis 4K demonstration material was simply better than the Sony store 4K demonstration material?
The bad news concerns how the 4K televisions look when displaying non-4K material. I had asked, but in the Sony store, with the 65" TV, they were not able, or chose not to, show non-4K material, though I did ask. In John Lewis, they kindly agreed to show non-4K material on the 55" screen. With broadcast High-Definition material, I think it was STV HD, I have to say that the 55" 4K Sony looked slightly worse than an ordinary 47" (I think) Full HD LED television showing the same channel, and worse than STV HD looks on my own televisions at home. But the real bad news relates to Standard Definition material. John Lewis kindly agreed to change the broadcast channel from STV HD to STV. The ordinary 47" television of course showed the drop in resolution from HD to SD. it didn't look too good. But on the 4K television, the SD broadcast channel STV looked - well, I can do no better than to quote from bigboss on post number 5 of this thread:

Also, SD content will look terrible on a 4K TV, due to the amount of upscaling involved.
In post number 8, the person who started this thread, ontheline (who seems to have disappeared, maybe he is "enjoying" his new 65" 4K television, especially with non-4K content) had said:

but it should make a considerable difference. sd content looks great upscaled
He couldn't be more wrong if he had said that water is not wet.
