I'll take your word for it. I have't seen most 4k LCD TV's
I don't know what you mean by "stretching" but I assume you mean "scaling" from 1080p to 2160p. I don't use any stretch modes at all, and agree that all stretch modes I have seen are pretty annoying.
For the handful of setups I have seen, the difference in scaling in the TV versus in the source is imperceptible to most people, including me. This is because, either way, a 1080p source has to be scaled to 2160p. This can happen in the TV (1080p source -> TV -> TV converts to 2160p for display) or in the source (1080p source, converted to 2160p -> sent to TV as 2160p).
In other words, there is usually no difference between scaling in the TV versus scaling in the source on the handful of 4k TV's I have seen from Vizio and LG, using ATV4k, Oppo 203, and Sony x800 as the source.
(I'm talking about 1080p sources. I have seen differences in how they handle 480i sources getting converted to 2160p, and agree that few TV's do as well at scaling 480i DVD content to 2160p as either the Oppo or the Sony players.)
And yes, for native 1080p content I find a 1080p set can be ideal in terms of no scaling artifacts. But the OP was asking about 1080p content unconverted to a 2160p display, and why the display did worse than the player in his setup.

The animated content I watch looks a lot better via the X800 than it does using the Philips 7302, my PS3 or any other I have ever used for playback. There is less noise, as in animated content it is easy to see when there is noise because there can be large areas of one color.
Yep, your eyes are not deceiving you, imo. See my comments above.
