Also consider this, Vizio processing power is probably the lowest of all the manufacturers. They don't spend a lot of money investing in fancy processors like Sony for example. So it is better to outsource the processing of videos to another device (Roku, Amazon Stick, Xbox, etc.). I use Vudu through Xbox one X. I have no problems with the TV and no problems with banding in UHD content. There are problems with HDX/SD content because it is blurry and lower quality. You also have to consider that Vudu as a streaming service itself is pretty bad. I often get stutters and bufferings while watching videos through that service.
1) HDX content on VUDU isn't blurry at all.
2) I don't believe your experience with stuttering and buffering has anything to do with VUDU as a streaming service.
What this comes down to is that HDX/4K content on VUDU should and does look great on Vizio sets. Vizio sets have no problem with 1080p content and higher. HDX is 1080p.
My humble main system:
Vizio M75-E1; Oppo 203 universal UHD player; Denon 4300H AVR, Dual PSA S1801's; Monitor Audio Silver RX-6 mains, RX center, and RX surrounds; one pair NHT mini Atmos speakers; Home-built HTPC (Xeon E1230, 16gb RAM, Crucial M500 480gb SSD, GeForce 980Ti, Corsair CX600, CoolerMaster mini-ITX case); Roku Premiere+; Amazon 4K Fire TV
