They lead in several areas such as video quality measurement (VMAF https://github.com/Netflix/vmaf https://github.com/Netflix/vmaf), robustness (Chaos Monkey https://netflix.github.io/chaosmonkey/ https://netflix.github.io/chaosmonkey/), video compression optimization (https://netflixtechblog.com/optimized-shot-based-encodes-for-4k-now-streaming-47b516b10bbb?gi=5eca1df094af https://netflixtechblog.com/optimized-shot-based-encodes-for...) and probably more.

I feel like they might be going a bit overboard with video compression optimization. As an example, Star Trek Voyager in HD looks significantly worse than OTA 480i. On the plus side, it looks good in 4k.

  I agree, their quality is sometimes questionable but to be fair OTA has preallocated/fixed bandwidth, while netflix on the other hand likely gains from optimizing for lower bitrates.

    They can optimize for lower bitrates, which they've been doing for a while, but the recent drop in bitrate is really awful. https://variety.com/2020/digital/news/netflix-degrading-hd-video-quality-europe-bit-rates-1234605316/ https://variety.com/2020/digital/news/netflix-degrading-hd-v... Even if they are bandwidth constrained, I wouldn't be surprised if some shows looked better at 480i/.5Mbps than 1080p/.5Mbps.

      Yes, and it's very frustrating too: they lowered the bitrate when Thierry Breton, the European Commissioner for Internal Market https://en.wikipedia.org/wiki/Thierry_Breton https://en.wikipedia.org/wiki/Thierry_Breton said the internet would not support the extra load due to work-from-home/COVID. Breton was CEO of Orange, internet & 4G provider. This is all sounds very suspicious, and it was clearly wrong. Some of us pay for UHD quality and we don't get what we initially paid for.
