Should the peak white luminance ratio of a display as described in the regulation be calculated using the brightest on-mode value determined in a configuration ?

The peak white luminance ratio as defined in the regulation should be determined in the brightest on-mode configuration which indeed can be a pre-defined setting (such as 'vivid', 'dynamic', etc.) in the set-up menu. If the end user alters any configuration - including the brightest on-mode - through adjustments of individual parameters such as brightness and this leads to increased energy consumption, this requires that warnings are displayed to, and consent is requested from, the user (cf. last paragraph in Annex II point B.2).
