Let’s consider the following facts:
VIDEO HDR data handling requires very high computational and storage performances, way above the capabilities of standard consumer and prosumer hardware.
Contents distribution market trend is definitely headed towards streaming technologies that offer limited resources, in particular a limited and highly variable bandwidth
A full HDR video stream contains much more information than what is perceivable, while a careful balance between different video dimensions can result in much improved viewing. Consider resolution, refresh rate and colour gamut.
These and other reasons justify a very lively research activity in HDR compression and parametrization for visual presentation. The HDR47E monitors are a very good testing tool, allowing to eliminate most of usual uncontrolled variables and even a direct access to the hardware
