Why more care has to be exercised when shooting/grading/delivering HDR than SDR

Clipped highlights that can be rolled off in SDR are unsightly in HDR. HDR is more prone to unsightly banding artifacts. Streaming bitrates must be higher to avoid blocking artifacts. Noise becomes much more of a nuisance in the shadows. Overstauration can make your picture look like cheap camcorder footage. The higher local contrast of HDR makes images appear sharper, which can be very unpleasant, digital-looking and unflattering to actors’ faces. Judder is much more apparent in fast panning shots and subjects moving in front of bright windows. Because the brightness of HDR content cannot be increased by the viewer, greater care has to be taken to ensure that shadow detail is visible on consumer televisions and mobile devices. But most importantly, because viewer expectations are much higher for HDR content than for SDR, consideration of all these possible pitfalls has to be taken into account at every step along the way.
