You are the best, many thanks Devrim.
I would just like to share these screens, where I actually found a semi-way of using them with quite ease. It is yes very bright, but it has a “studio” tone.
1. raw screen from Mac native player
2. raw imported in DVR (Rec.709A)
3. trying things which looks “okay” (if you have any input regarding making it a little less flashy)

Which screen or Apple product could I buy (the cheaper) to get a HDR-able screen ?
I can read here : https://support.apple.com/en-us/102205 that MacBook Pro have HDR screens since 2018 (so I could manage something on Backmarket), but for example here :
https://support.apple.com/fr-fr/111925
I see no trace of HDR capacity whatsoever, so I’m a little lost.

Final commentary, I just desactived HDR on my iPhone :D. For now.
