I want to be able to objectively evaluate the law of diminishing returns (eg. whether an b7 at £1300 is worth 2.5X an ex750) and cut away the marketting BS.
(Vincent should do crowd-funding for his reviews)
All the manufacturers are cagey wrt specs, and obviously push the the technical benefit of their (oled-blacks/lcd-colour volume) technology versus the competitors.
The we75x maybe 8+frc and the we6x 8, but it would be nice to know what an additional ~£60 is buying.
What you've just written is somewhat confusing: You want to "objectively evaluate the Law of Diminishing Returns". Why? It is already proven in economics.
Okay, I'm teasing you, but seriously; how exactly do you propose to objectively evaluate the cost benefit of the features of your example B7 over an EX750? There is no monetary value attached to black level or colour gamut or peak brightness. Even if you had a colorimeter capable of measuring very low brightness levels to make some objective measurements, the only thing it tells the user is that one is better or worse than the other. It's entirely
subjective whether a consumer feels that the benefits are worth the cost.
I take your point that manufacturers are "cagey" with specs. Something similar has already been said in this thread, and anyone with a passing interest in the technology will have probably worked that out for themselves. Thank goodness then for third party reviews done by people such as those at HDTVTest. But with the best will in the world, they can't evaluate every TV. For one thing, there just isn't the time before the annual model changes. Another factor is that, for the majority of TVs on sale, the consumers really don't care. If they did, we'd still have Pioneer and Fujitsu making TVs; and Sony and Panasonic wouldn't be losing money hand-over-fist in the TV market; and Tosh, Sharp, Hitachi etc wouldn't have sold off their TV businesses. You know, people wouldn't buy their tellies from grocery stores or book merchants. That's not the market today though, is it?
When this thread started I thought we were talking about 32" and 40" 1080p sets with HDR compatibility; and as I said before, I can see value in the 32" set -
LG does one as well - and possibly some value in the 40", though that is harder to justify. I wasn't aware of the 49" Sony. Unless similarly-priced 49" UHD HDR sets from competitors make a complete fist of SD and HD TV signals then the 49" WE66x is the one that I can't see having much market appeal.
