What kind of sensor?

Oversampling is always a good thing. Having a Beyer source at the same resolution as a colocated output was okay with SDR output, as the camera's much higher dynamic range provided additional details. But a 4K Beyer sensor for 4K 4:2:0 HDR content can be suboptimal versus capturing more, since the output can use the captured dynamic range.

I doubt it's that material in practice, though, since visually resolving individual 4K pixels is pretty impossible in moving video outside of specific test content. But supersampling can reduce noise some (although having smaller sensor elements adds per-element noise, so it can be pretty complex to model and predict).
