Do you mean if you don't have a 4K TV and streaming device? Or if your bandwidth isn't enough? I'm not sure how they downsample their Dolby Vision streams, since my TV definitely switched over into Dolby Vision. I suppose the Netflix app may be able to stream lower resolution versions still with the Dolby Vision metadata.
