Color Washed out after render

Hi EVCAM.

Welcome to the community! As Experts suggested, this could happen due to a mismatch in color space settings between your clip, sequence, and export. Please share a detailed screenshot of the options selected under Window > Lumetri Color> Settings tab and a screenshot of your Export Settings. It will help us guide you with the next steps to solve this issue.

Thanks,

Ann and PeruBob are right, you as the user need to tell the color management system what you want done.

It can do a TON of different things, they can't guess from those what you want. Personally I've been around, working for, and teaching pro colorists for years. I suggest staying in Rec.709 . 

Because unfortunately HDR is still the Wild Wild West and totally unpredictable from screen to screen. 

See here, too:

The problem is...I shooted video from Iphone 13 (model I don't remember)

Iphone Working Space Color is Rec 2100 HLG...and Premiere Pro works in Rec 709

That's why the problem is happening.
