Sorry to go against the flow but for balance I'm gonna post my experience in the hope it avoids others wasting their money.
No difference whatsoever! Had it in my system for 2 or 3 weeks and the only thing that was more 'vivid' was the debit from my credit card and the only thing that was brighter was my self awareness at getting taken in by this crap.
It's small potatoes compared to the money spent on the remainder of my system, so I don't really care and am happy to chalk it down to experience. But as the saying goes if it sounds too good to be true then it probably is.
I was amused at how big it is. But that has genuinely been the
only impressive thing about it so far
Sony AG9 Oled TV if that's relevant.
