You can render both resolutions natively but end up with different resolution.
You can scale a 1920 down to 720 but that is not really accurate to the 720 render.
A multi megapixel photograph can be scaled down to each resolution making both near native.
When displaying we don't have a viewing device capable of showing both at native resolution.
I think if you have a 1080p device, rendering a game at 720p and letting the device upscale it to 1080p gives you a pretty accurate image of the 720p render.
I went from 720p 3D on my native 720p Acer H5360BD, to 720p 3D on my native 1080p Benq W1070, and they're pretty close. 720p on the W1070 looks just a little better thanks to the smaller pixel structure of the projector, but you wouldn't mistake the 720p rendered image for a native 1080p one.
Downscaling (as with photographs or DeGoSaTo) I think is much more difficult to notice.

Answer if you can notice a significant quality difference playing 720p on 1080p display.
And if feeding 1080p to a native 720p display is better than outputing 720p.
3DTV Play is mostly about feeding a FullHD tv with a 720p image.
Resolutionwise there is only 50% more linear resolution compared to 720p.

720p on any of my 1080p monitors looks horrible. Doesnt matter if i let gpu nor monitor to upscale it. 720p looks pretty good on my 1080p projector though.
So is this a question on the thread title? Sorry, i get confused when you dont use question mark and state a few facts in op.
If you are trying to compare 720p vs 1080p image quality, IMO the only clear way to test and see the difference is via 2 different displays, preferably side by side. One is 1080p, one is 720p. I personally have tested 720p and 1080p at 120" and I still have dual mounted projectors. I use 720p 3d vision pj for gaming and 1080p for movies. While i couldnt exactly do a side by side comparison, given that i only have 1 screen and both projectors pointed at it, i still think it was rather easy to see that 1080p wasnt that big of a difference. For blu-ray movies, i actually struggled a bit to notice difference. It was there though. Games were easier to notice, because lower resolution gives you more jaggies. After applying a proper AA, it was harder to tell a difference. Still, 1080p is visibly better and clearer, but not so much that i couldnt stand 720p anymore. In 3d i had to compare in "still mode" because 1080p 3d was limited at 24hz.

I'm actually in the same situation. One screen, two projectors. I think TVs/projectors probably have better scaling chips than computer monitors, where scaling is expected to be done on the PC itself.
I agree with your criteria. To do an accurate comparison, you need a native 720p monitor next to a native 1080p monitor. Both the same size with the same image quality (contrast ratio, etc).

Thanks to everybody using my assembler it warms my heart.
To have a critical piece of code that everyone can enjoy!
What more can you ask for?
