CTA-861-G section 6.9.1 Static Metadata Type 1 declares that zero values
for different groups of HDR Metadata properties are allowed, including
zero nits values for max display mastering luminance, max content light
level, max frame-average light level and min display mastering luminance.
A zero value is meant to be treated by the video sink as "undefined" /
"unknown", and handled accordingly. This is common for dynamically
generated visual content.
Therefore don't assert on some minimum nits level > 0, but only check for
a non-negative level.
