I'm with you. Loving the picture with every source thrown at it, and don't want to wake a sleeping bear. I've even had the YouTube app open twice and resisted the urge.first time OLED person here and i went with the 55" CX. I have read all 132 pages in this thread and i am afraid to do any kind of grayscale tests. Anyone else refuse to do the greyscale tests?
I have watched several movies/shows that are dark, and have yet to see any banding issues in gray areas, even when actively looking for it.
Let your eyes tell you if it's good enough. If you haven't seen any issues, why go looking? Unless you want an excuse to return/exchange the set.
It is just important to keep this forum in context...
