Washed out colours in exported video. Why and how to fix?

Hello,

I'm using a Windows 10 PC laptop and the raw files (straight from SD card) from my GoPro 8 (for cycling) look great, vivid and colourful (2.7k 30 fps), but when I export it I get the video all washed out colour. Why?

Here's how it looks for me..

Original file when looking copied from SD card (Windows 10 VLC): https://ibb.co/dr2DJ1X

PP preview (looking same as original file): https://ibb.co/M8pJyFG

Exported file with washed out colours: https://ibb.co/TH1vNNL

My exporting settings: https://ibb.co/LhXF2Ps

I'm going mad honestly. None of the "solutions" I've found on the web work. For example the gamma corretion LUTs just darkens my final exported file more compared to the original from the SD card, also don't get why. How do I retain the exact same quality in exported file that I have in the raw file?

Thank you
