I just looked at it again side by side and I think they are actually the same. Not sure why I earlier thought they were different.

On a tangent, if I have a M3 pro laptop how do I test HDR? Download a test movie from where, play it with what?

I may or may have not seen HDR content accidentally, but I’m not sure.

You can search for videos on YouTube and filter by HDR. Apple TV shows are typically in HDR (Dolby Vision). Here are a couple of examples:

[0] Hawaii LG Demo: https://www.youtube.com/watch?v=WBJzp-y4BHA [1] Nature Demo: https://www.youtube.com/watch?v=NFFGbZIqi3U

YouTube shows a small red "HDR" label on the video settings icon for actual HDR content. For this label to appear, the display must support HDR. With your M3 Pro, the HDR label should appear in Chrome and Safari.

You can also right-click on the video to enable "Stats for nerds" for more details. Next to color, look for "smpte2084 (PQ) / bt2020". That's usually the highest-quality HDR video [2,3].

You can ignore claims such as "Dolby Vision/Audio". YouTube doesn't support those formats, even if the source material used it. When searching for videos, apply the HDR filter afterward to avoid videos falsely described as "HDR".

Keep in mind that macOS uses a different approach when rendering HDR content. Any UI elements outside the HDR content window will be slightly dimmed, while the HDR region will use the full dynamic range.

I consider Vivid [4] an essential app for MacBook Pro XDR displays.

Once installed, you can keep pressing the "increase brightness" key to go beyond the default SDR range, effectively doubling the brightness of your display without sacrificing color accuracy. It's especially useful outdoors, even indoors, depending on the lighting conditions. And fantastic for demoing content to colleagues or in public settings (like conference booths).

Ahh. Not Firefox, of course.

Thanks, I just ran a random nature video in Safari. It was pretty. The commercials before it were extremely annoying though. I don't think it's even legal here to have so many ads per minute of content as Google inserts on youtube.

Hah, I tried skimming through a 2 hour youtube video in Safari and every time i fast forwarded a couple min google inserted two ads. Basically I watched ads more than the video.

How can people use anything that doesn't run ublock origin these days?

They can keep their HDR.
