<td>Set the target display peak brightness in nits. This is used for
configuring hdr capacity max of gainmap metadata. This value determines
the weight by which the gain map coefficients are scaled during decode.
If this is not configured, then default peak luminance of HDR
intent's color transfer under test is used. For hlg, this corresponds
to 1000 nits and for linear and pq, this corresponds to 10000 nits.</td>
