I just found this: http://www.hdtvtest.co.uk/news/shootout-oled-201511134208.htm
"Outright colour accuracy was also better on the Viera 65CZ952, though the LG 65EF950V’s colours could be calibrated (using a specific technique) to a reasonably accurate level that’s not too dissimilar to those displayed by the Panasonic CZ952 and ZT65. The Panasonic OLED delivered superior above-black handling versus the LG: while some attendees praised the 65EF950 for revealing more shadow detail than the TX-65CZ952B, we thought that the LG was actually displaying them too brightly (and occasionally floated blacks even after we’d checked and rechecked that we used the correct [Brightness] setting using a PLUGE pattern), and the Panasonic was more accurate to the source."
This sounds like it was a side-by-side comparison against the ZT plasma and the Panasonic OLED using the same content, so whatever HDTVTEST was seeing was not content-related.
This has me concerned, since I have been assuming that the occasional cases of 'too-bright blacks' I have experienced were caused by improperly mastered content that was not conceived with 'perfect blacks' in mind.
If these cases of 'too-bright blacks' are actually being caused by the OLED (that the EF9500 is 'floating blacks' as described by HDTVTEST), this is a pretty serious flaw.
Have any owners experienced this?
Is there a way to test for 'floating blacks'?
If Panasonic has found a way to resolve this, hopefully LG has as well.
Any ideas for how to test for or understand this 'floating blacks' issue appreciated.
