This a great article that discusses that numbers are not the prime indication of performance. Its to lure the consumer into a marketing ploy. The bigger the contrast ratio numbers the more people believe they have a better picture.
The most important aspect that I got out of the article was:
"You won't be able to discern more than a 100:1 difference between the darkest and lightest objects. Of course, the instant your eye moves, its built-in auto iris function raises and lowers the grayscale boundaries. That's what allows you to perceive shadow detail and also pick out a white cat scurrying along in a field of snow."
This shows us that a 10,000:1 or 15,000:1 contrast ratio is meaningless to picture quality. We as humans can only discern 100:1 from dark to light objects. When I mention shadow detail contrast ratio is a direct reflection to obtaining a great picture. However, not 10,000:1 will indicate that it has great shadow detail.
So to answer your question, contrast, contrast ratio, grayscale, whatever you want to call it, qualifies my reasoning that it is important. Now the huge numbers, for example, 10,000:1 I don't agree with, but are not important or inaccurate reflection of measurement. My signature that I have below qualifies and supports the article that we have read.
That article was a good find...!
