The following BluRay 3D work, should all be retail although I rented a couple of them:
Kung Fu Panda
I either own or have access to rent quite a few on the sanderdvd list so I will continue to update if others do not beat me to it. Would be nice if his list was a sticky.
UMR on HDR vs 4K: The benefit of greater saturation and luminance capability is...not very evident in all images unlike more pixels which can be seen in every scene.
