Exporting HDR video to YouTube

Hello everyone,

I've a project I was working on it for months and I'm trying to release it, but the export results preventing me to do so.

I made huge amount of exports with different settings HDR and uploading them to YouTube.

Unfortunately, I ended up with videos that are either too dark, desaturate or washed colors or overexposed.

when I was desperate, I was even choosing 706 color space, and some scenes looks a bit ugly too much magenta i.e. magenta on the sky (while on the original it looks white blue).

Just for clarification, I don't own an HDR monitor but I'm using madVR in media player-BE which converts the HDR footage to SDR and it looks great on my monitor.

In the other hand the exported video colors looks weird, washed or desaturated I don't know how to even name it.

I do own and smartphone that support HDR (in case I want to check on YouTube) Regardless to the results, I've uploaded YouTube on private and I've checked on the smartphone & the video isn't recognized as an HDR content, however, it does look better to some extent.

The settings I've tried to export the video to are:

Format: QuickTimeApple

ProRes 422HQ, Apple ProRes 4444 (also, HLG, PQ)

HDR graphic white nits: 203

Color Space: I've tried both HLG and PQ

Depth: 16-bpc

maximum bit depth and render quality are checked.

As mentioned earlier, I've also tried H264 but it's also doesn't look good and I also don't want a compressed format.

The original video info according to media info:

File Format: HEVCFormat

profile : Main 10@L5.1@High

BT.2020 non-constant

HDR format : SMPTE ST 2086, HDR10 compatible

Bit depth : 10 bits

Resolution- Width : 3 840 pixels Height : 1 920 pixels

Bit rate : 16.4 Mb/s

Display aspect ratio : 2.000

Color space : YUVChroma subsampling : 4:2:0

If more info is required please let me know.

I'm using Premiere Pro 2021 V15.4.0

My pc specs:

CPU: AMD 5950x

GPU: 3080 (drivers are updated to the latest)

RAM:128GB 3600

Samsung 980 SSD NVME

Please help me with this.

I'm already 4 days trying to figure it out with no luck or real solution, feeling desperate reading so much on google and watching every YouTube video to find a fix for this.

Am I doing something wrong with the export settings I've choosen?
