Streaming uses variable bitrate. When your internet hiccups, the algorithm sacrifices visual complexity. In Doctor Strange , the most complex scenes (the folding city) are exactly where the algorithm fails first. With a proper UHD BluRay rip (especially a well-encoded X265), the bitrate is constant and high. The city folds perfectly .

But it is the correct way.

The X265 10bit encode, when done properly (by reputable release groups), retains the HDR10 metadata, wide color gamut (BT.2020), and the film’s original 23.976 fps. It is the most space-efficient way to keep near-disc quality.
