After some thoughts, I finally retired my beloved 2009 iMac 24" for the new M1 Mac Mini.
I connected it to my Xiaomi Mi 34" Ultrawide Monitor via Displayport, it works fine at full resolution (3440x1440) at 144hz, no problem on this side.
The issue is that it seems I can't find any good color profile on the system settings to address a certain fog looking effect, the blacks are kinda greys. I tried different setups, from big sur and from the monitor software but that effect it's always there.
The only profile from Big Sur that doesn't look washed out is the Rec. ITU-R BT.709-5, with some tuning on the monitor side (contrast, black lever etc...).
I can see this specially with dark mode, dark wallpapers and during the flurry screensaver, the areas that should be as black as possible are greys. On Windows there's a similiar screensaver and the blacks are deep as it should.
The monitor works well, I have a PC as well connected via DP and the blacks are deep and fine, on Windows I didn't had to touch anything, working with the default sRGB color profile and I only had to tune the values from the monitor.
I took some pictures of the black bars while watching a football match, top pic is windows, bottom one is the mac. You can clearly see the diffence in the black bars. Of course it doesn't represent well what you could see with your eyes here, but it helps to explain.
