What your opinion is isn't fact. It's subjective. Similar to audio and taste, it differs.
care to elaborate?
comparison with different content is apples to oranges.
with similar/same content, the difference is quite difficult to discern.

What!?!?!
Hell no!!!
HDR covers wider range of color gamut. You are able to display colors that normal monitor isn't capable of.

Think of it like TN vs IPS screeen


Even that image and the widest triangle shows that the difference in color intensity becomes extremely hard to discern the further towards the edge you get.

A difference may be measurable, that still doesn't mean we can observe it ourselves in any regular content viewing setting.

It is quite similar with high fps gaming. At some point, the difference becomes so small but it is still measurable, and because it is measurable, people are convinced going ever higher is going to keep giving them more advantage and perceived smoothness. At some point, higher numbers just enter the realm of placebo effect, and for high FPS gaming, that exists above 144hz, for color reproduction, similarly, there are other panel qualities that are FAR more important for good color and contrast but those are too expensive to implement, so we're made to believe we need silly stuff like HDR even though the current color space covers almost everything we can see with the naked eye.

There's a perceptual version of the CIE diagram as well. But the reason you can't discern colours is that your monitor doesn't actually cover the gamut in that diagram. No monitor does.

The main issue is that when you're covering more of the visible spectrum, having to choose between only 256 shades of a primary colour means you spacing those shades farther apart. Thus, more chance for banding.
For processing, having more shades than the eye can see is even more important.

This is like judging a singer by hearing friend of yours sing a song, that he heard on his concert.
