I wonder how a large organization does something like this successfully. Like you need your OS video driver team working with the application team and so on.

My impression is that PMing this is really hard. And then each of the other guys is going to have an opinion that this shouldn't be done because it's so rare, etc.

Something must be organizationally right for something like this capable engineering to have succeeded on such a barely noticeable feature.

I love it when products casually have cool things like this. Not quite the same scope but IntelliJ's subpixel hinting option has each element of the drop down displaying with the hints that it describes. You don't have to pick an option to see it. You can just preview it off directly.

Colorimetry is standardized. The W3C has been asking the same questions about mixing HDR and SDR, as have various other standards orgs like SMPTE: https://drafts.csswg.org/css-color-hdr/#Compositing-SDR-HDR

Mixed HDR/SDR content is interesting problem. To me the example where thumbnail is presented with HDR color feels wrong, because it makes the thumbnail to stand out in a distracting way and seems highlighted in some way. But the iPhone example on the other hand looks really good; note how it seems like it switches from SDR to HDR display when the picture is selected. For desktop, maybe the simplest heuristic for choosing HDR/SDR is if the the window is fullscreen/maximized or not.

> This EDR display philosophy is so important to Apple that they are willing to spend battery life on it. When you map “white” down to gray, you have to drive the LED backlight brighter for the same perceived screen brightness, using more power. Apple has your laptop doing this all the time, on the off chance that some HDR pixels come along to occupy that headroom.

This is a bit misleading. The backlight isn’t at a higher level than necessary for sRGB content all the time, just whenever any HDR encoded videos or EDR apps are open. When you open an HDR video you can see the highlights getting brighter as the backlight gets pushed.

This is simply not true; a lie. Everyone in Hollywood and the professional print world who needed color-accurate displays that could be calibrated were using HP Dreamcolor Displays or similar products from companies like BenQ

( For example: https://nofilmschool.com/2017/12/benq-sw271-color-management... )

No movie studio does professional color grading on anything else.

Apple has a functional organisation structure which is quite unusual for a corporation of that size.

I'm not sure it's as difficult as you suggest. As long as you don't let applications touch the pixel data of decoded images, it's all within libraries, and you can change the bit depth of buffers and change how they map to physical pixels easily.

Most frameworks don't let applications touch pixel data without jumping through some hoops, because by restricting it you can implement things like lazy loading, GPU jpeg decoding GPU resizing, etc.

I mean my Sony a73 is not Alexa or Red, but doesn't stop it being a high quality camera :)
