Thank you and sorry. I translated it on Google and forgot to copy the text in English.

I can understand why you come to this conclusion, but in practice this is not the case. It is covered more fully in this video (if you can tolerate the robo-narrator), but the gist is that the base HDR10 layer is usually a handicapped mix intended for the median consumer TV, and not high end displays. Thus it is frequently limited to 600 or 1000 nits brightness. You need the Dolby Vision metadata to restore the full fat mix, not by design of the spec but by mix convention.

I have these demos that show the video in HDR, DV formats in P7, P5, and P8, and each file is about 1 minute long. I received these demos to test on my Ugoos AM6b+ box with CoreElec installed, which reads all HDR and Dolby Vision formats.
If I watch them one at a time, I can't find any differences on my Sony Bravia 9 TV. Now, if I do it like the video you posted here, it compares still images in each format. You'll always find differences this way because the image is still and you can look for details. Now, if you're watching the movie, in this case the demos, after watching all three, I don't think you'll be able to tell which is P7, P5, and P8. At least I can't see the differences.

I would expect properly decoding P5, P7, and P8 to look virtually indistinguishable. The comment was directed toward DV vs base HDR with no metadata. I think the difference between the base HDR layer and the DV layer, no matter the profile, is meaningful.
