Don’t you have a Rec. 2020 Content – Watch only DCI-P3
After being so euphoric about the color space Rec. 2020 and preaching it like a prayer mill – almost like a sales pitch – to the man or woman or even the men or women, I had to realize something frightening. There is basically no content that can be used in Rec. 2020 was mastered. Do any of you know of a movie in Rec. 2020? If yes, please info to me. Please don’t get me started on the new Lego Batman movie…. Something real please!

Let’s look again at what we actually gain in visible colors when we move from Rec. 709 (sRGB) via the P3 to the Rec. 2020 Switch color space. In relation (see picture above), this sounds like a color revolution. That’s what I thought, too, until I took another look.
The green color range is where you gain the most. A little in the blue to purple range and there is also red on top. The yellowish area (at the right edge) is basically negligible. Hmm, and where does that leave us now? Very good question. Where do you need the most variations of green? Right, when you watch a nature movie. Then there is not just the one green forest, but the one forest in quite a few shades of green. And the sky will shine even more beautifully in the range of light blue hues. Who in Rec. 2020 looks into hell, the color red will also reveal itself – in even more variations. At the end of the day, it remains to be seen whether that makes any difference at all. For me, it’s now manageable and I’m going to curb my euphoria again!
Here is a summary of the requirements for HD or UHD TV and HDR. Not quite as important for gamers. This all relates to TV and streaming. Virtually everything you can watch on Amazon Prime Video, Netflix and co. can look at like this. If you look at the table, you would assume that this has long since found its way in. Unfortunately not, because I sat down and compared various movies on the LG C1 OLED with the ASUS ROG Swift PG279QM. I could not notice any difference here. Why became clear to me quite quickly. Don’t you have a Rec. 2020 content, then you can’t max out a wide gamut display. Everything runs nicely in the P3 color space. Rec. 2020 – Fiddlesticks!
Just for completeness, PQ Gamma comes from Dolby and is capable of up to 10,000 nits of brightness. Let’s assume the content is mastered with 1,000 nits HDR (Dolby Vision), then this curve (EOTF) is followed. Whether the display device can do the 1,000 nits is irrelevant. The situation is different with HLG (Hybrid Log-Gamma). Here, the peak brightness at the end depends on the display device. If the device can only do 600 nits, it doesn’t get above the EOTF curve anymore. This means that HDR content can still be rendered “passably” even on pure SDR displays. It’s time for the conclusion, so last page.
