Thx Sc53. I remember all those Bly-Ray samples for the sales floor demos. Especially cartoons. All just designed to 'wow'.
Now I have adapted to BluRay quality via HDMI to our upper end plasmas; and I now find DVD's picture quality lacking! Whereas I can still remember first seeing a DVD on whatever was then top line TV, Steven Segal flick on a boat. Girl jumped out of cake,etc--and I almost never remember movies..
I think 4K is stunning, as it should be, but i"m still satisfied with BluRay on my panny for now. I expect "8k" is not far off and then I think it will be like the airline industry- comfort similar in all top models. No going to 4 wings or 6 engines, it flies as is. I think much of the annoying unnaturalness was due to adjustments of brightness, color saturation or hue, contrast etc.
