This monitor received a firmware update a couple months ago, MCM104, addressing abnormal skin tones at 100% brightness using HDR and loss of shadow detail.
I am on MCM104 right now as it says in the monitor OSD, 100% brightness is still completely broken. It is not only still causing loss of shadow detail, it is drastically changing yellow/orange colours and adding this greenish hue over them, which is making things look terrible. This issue is most notable in Cyberpunk 2077, where during a sunrise or sunset, everywhere the sun is shining has this horrible green-yellow colour. It is also noticeable on any HDR videos that show yellow/orange colours.
Changing colour temp does nothing(I am on 6500K), and if you switch back and forth between 90% and 100% brightness, you will notice 90% brightness is showing all yellow/orange colours as intended and shadow detail is retained. Which is a shame because the extra 400 or so nits in small specular highlights really adds to the image.
I know I'm not the only one who has this issue as someone else posted about it, but I haven't seen it talked about other than that one person so I want to bring it up again - it's an issue which I feel can be completely fixed on your end. I cannot take photos either as my phone camera isn't good, but ANYONE with this monitor can change between 90% and 100% and see for themselves.
