Has anyone with a B6 on 4.31.20 found a way to watch Disney+ in HDR without the disastrous color banding issues? Since the internal app isn't available on the older firmware, I tried loading the app on both a Roku Ultra and an NVIDIA Shield TV (2015), but both of their outputs suffer from the banding issues known in the 4.x firmware revisions. Is there any streaming device currently available that outputs in 4:2:0 10-bit format at 23.976Hz for compatibility with the 4.x firmware revisions?
EDIT: It looks like the Roku has a forced 4:2:0 10-bit mode in the advanced settings that works alright. For whatever peculiar reason, though, that mode isn't compatible with my Marantz NR1606 receiver (still get the banding), so I have to run the Roku straight into the TV and feed the audio back through to the ARC to the AVR.
