Transcode HEVC HDR to SVT-AV1 HDR with proper grading for HLS streaming

I'm currently trying to encode a mp4 containing a HEVC 10 Bit stream with proper HDR grading to a HLS stream in two codec versions, the first is HEVC and the second is AV1. The issue here is that the two encoded versions differ from each other according to the color grading. The SVT-AV1 version looks much colder compared to the HEVC grading.

These are my commands:

SVT-AV1

I'm using the following script to get the grading: https://pastebin.com/AZdKbPEL But to me, it seems that the encoder ignores these values, talking about SVT-AV1. Can somebody provide a little help here?

I would expect that both version looking the same.
