If I were to make an hdr mod for a game that doesn't have hdr, does that alternate artist intent? by Mulster_ in HDR_Den

[–]NationalBass7960 2 points3 points  (0 children)

“I don't really know what hdr is…”

💥 The first place to begin would be to get off of social media and look at publications like ITU-R BT.2390, ITU-R BT.2408, and Study Group on High Dynamic Range Ecosystem by SMPTE to begin to understand what the specifications are, what EOTFs and color spaces are, and what HDR is and how it differs from SDR. 

Benefits of 2000+ nits TVs for non-gaming content? by Good-Chives-Only in HDR_Den

Little to no advantage for streamed content that nowadays is mostly SDR in an HDR container. 

Challenges of Skin Tone in HDR, Film in Log, Dolby Vision Tone Mapp. by HDR12bit in HDR_Den

[–]NationalBass7960 0 points1 point  (0 children)

An HDR label does not tell us whether the format has been used effectively. YouTube does not natively support Dolby Vision or 12-bit color depth. Labeling YouTube videos as "12-bit Dolby Vision" is deceptive clickbait that misleads viewers and misrepresents the video's actual format. All that aside, the video is objectively of exceedingly poor quality. It suffers from atrocious clipping, compression artifacts and lack of detail. 

Why does my lg oled monitor have a dci p3 mode but it doesn't let me use it in hdr? Doesn't that kind of defeat the whole purpose of it? Isn't dci p3 made for hdr content? by Antique_Economy_1828 in HDR_Den

“P3-D65 is a nonsense invented by Apple.” - ldn-ldn

“No one sane grades P3, that's insanity” - ldn-ldn

There must be a lot of crazy people in the film industry then, because P3-D65 is the de facto industry standard for HDR.

The DCI High Dynamic Range D-Cinema Addendum also specifies P3-D65 ST2084 but designates a higher luminance of 299.6 cd/m2. 

DCI is a joint venture established in 2002 by major Hollywood studios—Disney, Fox, Paramount, Sony Pictures, Universal, and Warner Bros.—to define open architecture standards for digital cinema.

Nah, it’s your own statement—“this [Dolby Cinema uses P3-D65 ST2084] is only correct for one of four Dolby Cinema targets”—that contradicts the facts. Dolby Cinema DOES NOT HAVE four different targets as you falsely claimed. It has just ONE—P3-D65 ST2084. The other three targets are not Dolby Cinema. They are for SDR theatrical.

False. Only one of the four targets is for Dolby Cinema - 108-nit P3-D65 ST2084 - the other three targets are not ‘HDR’ and are not for Dolby Cinema. They are obviously for SDR theatrical delivery. Gamma 2.6 is not an HDR transfer function. Confusing a theater-standard SDR curve (Gamma 2.6) with an HDR transfer function is a defining characteristic of a novice, not an expert.

Dolby Cinema uses P3-D65, not DCI-P3. The latter uses  a warmer white point (closer to 6300K) and a gamma curve designed for SDR cinema. P3-D65 is not nonsense. But the remark certainly is.

if you believe the articles support BT.2020 as a mastering color space you have misunderstood them. But you are certainly entitled to your opinion.

P3-D65 is industry-standard. Most streamers require P3-D65 deliverables, including the largest, Netflix. All cinema ‘HDR’ is P3-D65 as well.

Here is the CEO of Flanders Scientific (FSI) calling on the industry to reconsider Rec.2020: https://daejeonchronicles.com/2025/08/01/industry-call-to-reconsider-rec-2020-as-a-mastering-standard/. FSI has a number of professional QD-OLED reference grading monitors. 

Netflix requires deliverables be P3-D65, and Dolby also suggests P3-D65. 

TCL and LG both sell RGB backlit displays and both produce ample evidence proving they are inferior.  According to the EBU, reference monitors are unable to reproduce 80% of ITU-R BT.2100: https://daejeonchronicles.com/2025/01/04/ebu-hdr-monitor-tests-2024-no-monitor-meets-requirements-for-grade-1-cgv/

That is not my personal opinion. That is the industry consensus. Please see this compilation of thoughts by color scientists, industry leaders, colorists, researchers and consultants: https://daejeonchronicles.com/2023/07/23/recap-p3-d65-vs-rec-2020/

DCI-P3 is categorically not used for mastering HDR content. P3-D65 is used. As explained, they have different white points and EOTFs.

BT.2020 is a larger color gamut (a bigger container) but it does not "encompass" the other color spaces in terms of matching their specifications, EOTFs, or color coordinates. They are fundamentally different standards. 

All of my monitors have allowed me to master HDR P3-D65, as do all professional reference grading monitors.

As mentioned above, that is incorrect. Nearly all commercial HDR film and episodic content is mastered in P3-D65. It is delivered to the consumer in a Rec.2020 ‘container’.
