To use the clipping patterns, you need to know what to look for. Because unlike SDR patterns where each band shows a different level, in HDR there are lots of levels between each band. So you could look at a pattern and think "I'm not clipping" when in fact you are clipping. This is especially the case if you're not careful in the way you shape the roll off. No time to get into details, but when looking at HDR contrast clipping patterns you want to make sure that the tone between each band is significantly different. If it's similar or barely distinguishable, you are most likely crushing levels due to the shape of your curve.
This is why some prefer looking at actual content, but that causes other problems because there is no way to know which levels the content has unless you use Arve's tool to show the clipped levels. I find this to be a better solution that to simply use actual content, but you need to set the tool to show the clipped areas.
Short answer is the white clipping pattern are very relevant even when using Arve's tool, as long as you know how to use them, but there are other/better ways to check for clipping, both using the tool and using real content
One of my favorite real content clips to use to check for detail is the clip from The Shallows where you see the waves (for example breaking on the cliff). If you're clipping white, you lose a lot of detail in the white foam. I also use the clip from Mad Max during the sand storm, for example where Max is hanging at the back of the car before it explodes, or during one of the explosions. I posted in the main thread how I used this clip and how to set Arve's tool to show clipping.
