Web source 167,57.

Then I have generated a lut3d with -m 130 -l 5.66 for HLG conversion. 5.66 means 2.5 stops more brightness. Results are good but I'm not sure.

Any experience or ideas?
Going by your command line there, the movie grading is a disaster.

I might pick it up just to see how bad it really is. So far, Alita: Battle Angel is the worst I've run into simply because it's a direct cinema XYZ transfer to PQ with botched metadata.

EDIT: Wait a sec...130 for MaxCLL? This movie is also a naïve XYZ transfer. Here's your command line:

pq2hlg -s 65 -r 48 -m 130 heat.cube
