Mavic Mini 4 Pro HLG vs D-Log M, high dynamic range

I was very surprised to see that at the same exposure settings HLG retains better detail in highlights when shooting high dynamic range video. However the shadow detail seems to retain more colour information and detail with D-Log M.
I certainly need to experiment some more as I created very challenging conditions for the drone, but HLG may just be better for those sunset shots where highlights matter!
I think that with D-Log M you may need to underexpose by at least 1 stop to stop clipping.
In the video here I was 0.7 stops under exposed to retain highlights using an ND filter. HLG was about right, maybe -1EV, where as D-Log M may need as much as -1.3EV or even -1.7EV.
I'd be keen to hear in the comments others thoughts on this as i'm new to the drone and its log format.
