2020 color space hype?

Is this rant about 2020 hype valid? I'm not an expert, but I suspect some of you dudes are. (Mods: I couldn't figure out where to post this. So move it if necessary.)

Seriously, So all movie content is in P3 color space? Makes sense to me why OLED color still looks awesome despite inferior BT.2020 specs. You may want to post this in the OLED forum since one of the things OLED owners like myself have been wondering is why QLED colors are ranked higher than OLED on RTINGS, but real life comparisons with real content show zero color improvement on the QLED tvs. This pretty much explains it.

You post it there if you want; I'm an LCD guy and never look at the OLED forum.

BT 2020 sounds good but it is limited. DCI-P3 is used by movies since it covers almost all of the possible reflected colors. (see https://www.tftcentral.co.uk/article...ters_gamut.htm )

Remember movies are played in theaters with a reflective screen. So, even if the projector produced a color outside of the reflected possibilities it would not be any good since it has to be reflected off a screen that would not show the original color to the end user. There are some blue-green colors not in DCI-P3 bounds that could be reflected off the screen that are covered in BT 2020, but a lot of the additional colors in BT 2020 can only be created by computer (i.e. not filmed or video since those are reflected light) and need direct view to even be seen.

BT 2020 does cover almost all of the reflected color possibilities. But, the movie industry has little incentive to go beyond DCI-P3 since it covers most of what they produce by filming or video anyways.

Same type of situation in audio where speakers and equipment is sold on things like 10hz-40k he specs when absolutely no one can hear that range. To test equipment and other species of animals, the sounds there. To humans, not so much.

I’m sure the colors could be produced by the TVs with BT2020, but apparently the source material simply isn’t there.

Mike, the automated like isn't enough for the informative link you posted. I'm thoroughly enjoying slogging through it. I owe you a beer!

Yes it is true.. Vincent from HDTV did a video about that topic too..

It also makes alot of sense from a "work flow" perspective. DCI-P3 is the color space used in cinemas.. So they work in movie or tv production with this color space.. scale it down to Rec 709 for SDR, and use DCI-P3 for UHD and cinema..

Also DCI-P3 has a wider color range by Rec 709, but not far away.. You could calibrate even old SDR TVs to that color space.

They should haven chosen DCI-P3 as the UHD color space..

Vincent also said in that video that Spiderman into the Spiderverse had color beyond P3.
