My experience prior to this TV was my XBR8... which was excellent. I don't remember any advertising that said that 4k upscaling by any other device would be helpful. But I suppose you are trying to achieve perfection of your audio. I'm so knocked out by the great audio from the TV itself that I am less inclined to flip my super sound buttons. It seems to me that my blu-ray to external audio continues as it was before the new TV. 5.1 dts and 7.1 dts via blu-ray are unchanged. My Sony contracted tech guy connected system. I guess you could say I am too happy with everything... to seek more perfection, ...yet. Right... we are just never finished are we? I want to be finished. Everything is breathtaking. I recorded a 1080p opera from PBS a few days ago and sight and sound are magnificent. It's hare to believe that it's this good before you ever look at full 4k. The 4k image when fully 4k produced is impossible to describe to people have not seen it. I would say the effect is as though we had hdmi sockets implanted on the back of our heads. We see exactly what the 4k camera saw.
I think Jerry's issue - other than wanting everything to work as it should - is that he may want to test the upscaling using different components in order to determine which does it best. It is quite possible, but not guaranteed, that the Sony panel may be the best upscaler in the system - but Jerry has upscalers in his AVR and in his BD player too, and it is possible that either of them might upscale better than the panel itself.
Chances are, any differences at this level of gear will be small, but it's worth knowing. I have always done my upscaling via my dedicated Video Processor, for example, and I would be very unhappy if this did not 'talk' properly to my display (not that my VP will do 4K upscaling anyway, and nor do I have a 4K display anyway :)
I've seen some 4K demos and the quality has been variable. The most important thing is the underlying quality and ability of the display itself. 4K is LCD and as we all know, some LCD panels can have all sorts of issues - weak black level performance, poor off-axis viewing angles, problematic motion handling, hotspotting and so on. 4K is no guarantee of quality - just higher resolution. So the most important thing, for me, would be to ensure that the underlying display was the very best (as the Sony may well be of course). I have seen 4K displays that were, frankly, very poor by comparison with, say, a top of the line 1080p plasma from Panasonic. Others have been very impressive and allow one to sit closer to the screen without being able to notice issues that may reveal themselves in 1080p at such a distance.
I think that 4K has already been taken over by the marketing guys now, who are touting it as 'guaranteed better PQ', but nothing is further from the truth. Nevertheless, I expect people to be taken in by it and to assume as a result that if the TV is "4K" then it is automatically better than any 1080p HD display.
Fortunately, by all accounts, Sony have got it pretty much sorted - their 4K display I saw in a store environment looked terrific, even in the store. I am guessing it was set up by a Sony Rep and not by the kid in the store who normally does these things ;)
