Exported clip before encoding: Pink Joi Hologram Scene(https://mega.nz/file/Rg8RBJxA#ox5kgGUYfFKGZYMjzP_pzp-DD3dVcz3rlE5CH9mlPmQ)
I decided to leave the end of that yellow/orange scene to test different visuals.
Note that this clip has been compressed a decent bit just for the purpose of linking it here.

BV's Suggestions

[change the] pixfmt, color primaries, turn on hdr, etc [settings]
take that as a starting point, read ffmpeg and av1 documentation, see if you can do it

Using ffprobe to get color information

ffprobe -hide_banner -loglevel warning -select_streams v -print_format json -show_frames -read_intervals "%+#1" -show_entries "frame=color_space,color_primaries,color_transfer,side_data_list,pix_fmt" -i Blade.Runner.2049.Pink.Joi.Scene.BluRay.2160p.TrueHD.Atmos.7.1.HEVC.REMUX.mp4

Output:

            "side_data_list": [

                    "white_point_y": "16450/50000",
                    "min_luminance": "50/10000",
                    "max_luminance": "40000000/10000"

                    "max_content": 457,
                    "max_average": 179
                }
            ]
        }
    ]
}

We are now going to take all that data, and break it down into groups of <color abbreviation>(<x>, <y>) while leaving off the right side of the in most cases*, so for example we combine red_x "35400/50000"and red_y "14600/50000" into R(35400,14600).

Output: I don't know enough about encoding yet but 288MB to 12.8MB while still being this quality in 44 with HDR10 is really fucking cool
