No I don't have banding,
but It's easy to mess up the different settings and get this problem, then it's a good way to know that something is messed up in your workflow.

The saved image is fine, so this may be a bit depth issue on the display of the image within the render view, is there a place to change that via preferences?
It's not so simple, there are many different way to trigger this problem in renderView:
- dithering is missing for displaying linear image in renderview if Dithering is disabled in the Display menu of the renderView or if dithering is not enabled in Octane Imager settings.
- double gamma : using an Octane camera response + using Maya color management
- 8 bit depth limitation, if linear workflow is not activated by selecting an Image format with 16 at the end and if color management or Maya widget for contrast/exposure is used.
There is not one solution, it depends of your workflow:
- are you using linear workflow and maya color management, or are you using Octane tonemaping in 8 bit, or are you previewing HDR but with tonemaping HDR option enabled ?

I am also finding performance issue with the render view at larger resolutions. If I have a render view open of 2K plus then maya's interface gets very laggy. Again I would say that this is not a octane specific issue.
I don't have this issue but you are not alone, look at this Topic :

Many other render engine have their own render view of course, so if we are relying on Maya's inbuilt view and it comes with bit-depth and performance issues that would be a shame.
Indeed it would be nice to have access to the OctaneViewport from within Maya, I 'm pretty sure it is possible with the octane SDK.
