Last night I rewatched on HBOGO on a Roku vs the Amazon stream from the built in app on release.
Both had issues with banding, blocking and flashing. Mostly better on HBOGo last night. For example the night sky scenes where faint clouds are visible were ok on HBOGO but a blocky mess on Amazon.
I think this episodes is basically a torture test for any kind of compression. It is meant to look this dark. There is no light source in the content, nor is there meant to be. While I wouldn't be surprised if HBO tweaked things a bit for the disc release, it is meant to look dark. I would say 90% of the artifacts people are seeing are from compression.
I am on .15 still and when I rewatched the entire series I started with my digital copies through Vudu and switched to my blu rays after seeing similar issues in dark scenes. Those issue where not present on the discs. I did not have flashing issues. This is the first time I have seen that issue crop up and I wonder if being on .31 with low end gamma corrected they would still be present anyway.
Also, the audio for this episode was unusually low ands compressed on both platforms. I had to turn it up much more than any other episode of GOT and it still sounded flat.
