Non ho capito bene: pretendi di vedere bene con la luce impostata al 100% quando, specialmente in una sala oscurata, dovresti state intorno al 50%?! 
Prava a dare un'occhiata a questo filmato:

Ti spiego.
50%-100% sono valori che non contano nulla.
In un sala con una luce ambientale bassa, molto soffusa, si calibrano i TV a 120 cd/m2 solitamente. Che per un TV puo' essere il 30% per un altro il 60%.
L'affermazione " in una sala oscurata deve stare intorno al 50%" è molto spannometrica e poco correlata.
Ciò che ho affermato io, è semplicemente che essendo in un centro commerciale illuminatissimo, l'illuminazione l'ho impostata al 100%: non avevo del black crush a causa della scarsa illuminazione del TV.
E cmq con il sony lcd, vedevo molti più dettaglio dell'oled nelle zone in ombra.
In ogni caso, in questa review del G6:

si afferma ESATTAMENTE quello che ho rilevato io:
Contrast & Near-Black Performance
It’s widely known that OLED displays can shut off their pixels entirely and produce a true shade of absolute black. What hasn’t been so easy for them is to correctly and evenly light pixels that are fractionally brighter than completely off. Perhaps as a result of this, the LG 65G6’s [Brightness] control (which governs black level) is set to discard some dark-scene details by default. We found that we had to raise it by a decent number of clicks from the factory position of “50” in order to avoid this.
After doing this, during our dark-scene, dark-room testing, we noticed the blacks “floating”. During cuts to black, we could see swathes of non-black areas lighted on the panel, which is probably why LG crushed blacks by default. We agree with this decision, because this issue would be more visible than a small amount of black crush. However, the factory setting discards an excessive amount of shadow detail, more than we found necessary to avoid the panel lighting up slightly when it should have been completely dark. For this reason, we went back and forth and reduced the [Brightness] control by only a few clicks.
We analyzed 1%-5% stimulus levels on the OLED65G6P, and as expected, it was under these conditions that uniformity errors were most apparent, but to reiterate, we feel they’re now at the level where most users won’t be hugely troubled by them.
Quindi il black crush è intriseco di questi pannelli oled. Te lo tieni e basta. Ciccia.
