Pretty much as I thought, HDR makes no difference.

iPhone X Versus a non-HDR 4K display. Honestly the colors looks more similar than this in person, there is hardly any difference.

It doesn't mean the iPhone X can't look better, if I turn up the brightness, the amazing contrast will kill the LCD monitor obviously, but that ability isn't dependent on HDR content or video. I can do that with any existing content.

If you know what HDR is, and you think about it, you would realize there are two primary reasons HDR will look better:

1. high hardware brightness and contrast ratio (which doesn't work when you manually reduce brightness)
2. the higher contrast ratio makes higher bit-depth visible to the eye (but the iPhone X doesn't have high bit-depth)

The first reason works on all content, not just "HDR" branded content.
The second reason doesn't work because it isn't available.
If you have an LCD device like the iPad Pro 2017, iPhone 8, then nothing will work. It will just correctly convert an HDR image into an SDR image. And yes I tried that too with the iPad.

What's the take-away story here, don't obsess with the "HDR" lable, all you have to do is play any content, and just turn up the brightness. (When you play HDR labeled content, the system automatically does this)
In fact you don't need an iPhone X for this, it's the same thing with any OLED device with a decent peak brightness.

However this will NOT work with Youtube videos that are HDR. Because it isn't recognized, the image gamma will not be correctly converted. In a weird way, you have to watch a stream that isn't HDR for it to work correctly.

HDR makes tons of difference if the display and content is right. I see it myself on my PS4 Pro with HDR enabled games.
I have a X as well, but haven’t tested anything HDR related on it yet.
Some say that it has an 8-bit panel, so it could be one of the reasons why the X is not so great for HDR content to begin with.

There are 2 HDR standards

HDR10 And Dolby Vision But those are just Marketing terms the details are what matter.

HDR10 works on 10-Bit displays as in 4K HDTVs
Dolby Vision also works with 10-bit Displays But goes up to 12-bit

It is unknown if the iPhone Display is 10-bit.

So I think HDR on IPhone X has been debunked and is just there to bamboozle people.

There's so many things wrong with your post I won't even try.

HDR tv have 10bit support, which the iPhone X does not, there is just no detail in the shadows even when watching HDR content.

I think Apple is waiting to do 120hz and 10bit in one go. It makes sense since a new display driver chip is needed for either of those, might as well do it in one go.

Or you just don’t know anything.

There is also dithering that many manufacturers use on 8-bit panels to imitate 10-bit quality.

I think you're missing the point of HDR (and the screen shots you attached on your post are not good examples of it). It's supposed to highlight bright objects on the screen, like lightbulbs, the sun, lightning, etc. It is more effective when the scene has dark parts or better yet, a dark scene with sudden flashes of light.

Watch the beginning of Pacific Rim 4K Dolby HDR from iTunes (which I'm an actor in, BTW) on the iPhone X and notice the lightning effects, lava, lights on police cars, fires and explosions....they affect your eyes like in real life! You don't have to set your screen to maximum brightness to experience it but you can do so for a more blinding experience. Just don't squint or you'll miss it.

Good post.
Overall, HDR highlights bright details while preserving details in dark spots/shadows without crushing them. It also uses wide color gamut, which the X supports.

HDR10 is 10 bit chip system that utilizes 1.07 billion colors that uses static metadata meaning the metadata for picking the ranges is per video. It requires a 10 bit display chip.

Dolby vision is a 12bit software system that utilizes 64 billion colors that uses active metadata meaning the colors are adjusted in every shot. it is software based and only needs compatible media.
