Expectations and Understanding Limitations:
The HDR Preview Modes are incredibly powerful as a very affordable HDR signal monitoring solution, but they
do not represent a replacement for reference level HDR displays. Specically, while the Soft Roll functionality
does allow users to continue to see highlight detail present in the signal, something no SDR monitor will be able
to do well is mimic the color volume of an HDR display.
Users are sometimes surprised to note that one of the more apparent visual differences between a true HDR
display and an SDR display in HDR Preview mode is not always so much a perceived luminance difference, but
rather a perceived saturation difference. It is precisely the HDR display’s ability to preserve saturation at high
luminance levels that give it a much larger color volume. The increased perceived colorfulness of HDR displays
is physiologically explained by the Hunt Effect, which in essence describes a visual phenomenon whereby any
xed chromaticity (or you may want to think of that as any xed combination of hue and saturation) appears more
colorful as you increase its luminance. With this in mind, we see that the SoftRoll function may serve users well
for tasks like protecting highlight detail, but color-critical decision making should be left to proper HDR monitoring
on a professional HDR reference display.
