I'm sure if I saw a 10 primary display sitting next to an RGB one for reference, I could tell a difference. But if it was just sitting there by itself, in regular non-ideal viewing conditions, I doubt I would think that it is significantly better than normal displays. Whereas for high frame rate and high brightness/contrast displays I can easily see a big improvement under normal non-ideal viewing conditions without needing a reference.

Again, it would depend on the content shown. If you watch a 24 frame/second video on a 120 Hz computer display, I’m not sure you’ll notice much difference. If you use an extremely high contrast display to show a low-contrast image, you won’t see any obvious difference. If you use a 4K display to show a 240p video, you won’t see any obvious difference. If you watch a video with monophonic sound on a 7.1 sound system, you won’t hear any obvious difference. Etc. If you look at a photo produced by an RGB digital camera, color graded in some standard RGB space, and then presented on an RGB display vs. a 10-primary display, you aren’t going to see any obvious difference, because the content does not take any special advantage of the medium. In comparison, if you look at a bunch of synthetic images created to highlight the differences / stretch the capabilities of the displays, or e.g. a video produced by a whole hardware–software–author pipeline expecting the more capable display, the differences will be pretty obvious.

  High frame rate benefits all interactive content, and touchscreen interaction especially. High brightness and contrast benefits most content generally and practically all content under bright viewing conditions. But even if you upgraded all of your content to high gamut, I think only a small fraction of it would benefit in any noticeable way.

    It would be noticeable if all content authors were experienced in the medium, but in the transitional period there would be little obvious difference, because the entire culture of digital imaging, including almost all existing content, is based around the limitations of RGB displays and images. If you want a somewhat relevant test, you can try comparing images produced by a photo printer with images printed in old newspapers. Having a larger gamut makes the former much more vibrant. Current displays produce very intense orangish-red, purplish-blue, yellowish-green, and reddish-purple colors. So the differences with a hypothetical >5-primary display are going to be most noticeable in the blue-green range, and oranges and yellows.
