Blocky artifacts are the result of poor bitrates. In streaming services it's due to over compressing the stream, which is why you see it when part of a scene is still or during dark scenes. It's due to the service cheaping out and sending UHD video at 720p bitrates.

    Look, this is just an incorrect oversimplification of the problem. It's popular on the internet but it's just factually incorrect.

    Here's a thread discussing the exact problem I'm describing

    The issue at play for streaming services is they have a general pipeline for encoding. I mean, it could be described as cheaping out because they don't have enough QA spot checking and special purposing encodes to make sure the quality isn't trash. But it's really not strictly a "not enough bits" problem.
