Quality issue on Ipad

Hi guys,

I'm using Premiere Rush on IPad and I have a really loose of quality when I import video into Rush.

The quality is normal on the SIM card. I get full quality over the different device on my ICloud. But once I import the files on Rush I can see a huge difference on colours, pixels and everything...

I add some screenshot sorry i don't know know if that's help a lot.

I'm using;

iPad Pro 12.9 / 14.4.1

Premiere Rush 1.5.54

GoPro9, 4K 60fps

Thanks for help,
