InfinitiВот что пишут в руководстве пользователя по поводу выбора отображаемого диапазона цветов.
Установите для цветовой гаммы режим Автоматически, чтобы обеспечить автоматический выбор в соответствии с типом сигнала, или настройте отображение более ярких и насыщенных цветов, выбрав режимы Расширенная и Широкая. (англ.
Set colour gamut to Auto according to the signal, or display more vivid and richer colour in the order of Extended and Wide).
Т.е вторые два пункта принудительно усиливают слабые (ненасыщенные) цвета, но в то же время расширения цветового диапазона не происходит, это просто такой "улучшайзер".
На форуме avforums.com была по этому поводу похожа
дискуссия в ветке по B6V участием профессиональных калибровщиков, пришли к выводу, что самое корректное ставить Нормально (у нас аналог Авто). Приведу тест дискуссии здесь:

Hey Steve, we hear many well-established experts and calibrators confirming that Standard HDR already includes Wide Gamut even though the on-screen display may indicate 'Normal Gamut'. Do you agree?
Steve:
I'm not quite sure I understand your question
Me:
From Chad B:
Normal is most accurate. Extended is very close and ok to use if you like things balanced in the more saturated direction.
As soon as it gets an HDR signal it goes to P3 in a BT2020 container.
Wide and to a lesser extent Extended just over saturate lower saturation levels; they do not extend the gamut out any farther to P3 or BT2020
From Canary_Jules:
Chad B is absolutely correct. Wide and Extended just oversaturate lower saturation levels. Normal is most accurate.
and
Wide doesn't extended the Colour Gamut any further than Normal does - it just oversaturates everything within the Colour Gamut
Steve:
That ties in with what LG's engineers said, although interestingly if I send an HDR signal (DCI within Rec.2020) to an LG OLED in Normal mode it doesn't measure anywhere near 98% of DCI-P3, I have to select the Wide mode to get that kind of coverage. However it's possible that my signal is missing some metadata necessary to trigger the TV to map DCI within Rec.2020 correctly. It does make you wonder why LG even bother to include the Extended and Wide colour spaces.
Me:
I dont understand your answer...Are you agreeing with them? Does selecting Wide Gamut only over-saturate lower saturation levels without really extending the gamut any further?
Steve:
I'm saying that my findings don't agree with them but LG's engineers say you should use the Normal setting for HDR content, so what they're saying makes sense.
