Colors from iPhone video extremely distorted

I filmed some videos with a co-worker on her iPhone 14 Pro Max, when I created my sqeuence and dragged my footage into it, I selected "keep existing settings" when the prompt came up, then the footage looked like the first image (blue and bright orange) here. When I went to screenshot the video in Premiere, the still turned out like the second image (very grey). 

I made a new sequence and dragged the clip into it and this time selected "change sequence settings" and the footage looked perfect, when I exported the footage, it looked like the last photo (bright blue and yellow).

I noticed the original files were recorded as HEVC files so I converted them to .mp4 and when I dropped the clip into the timeline and selected "keep existing settings" it looked like image 4 (blue shirt but very blown out looking). When I selected "change sequence settings" and exported the file, it looked like image 5 (blue shirt but distorted arm color).

I have no idea how to fix this or what to do!! Can anyone help?

iPhone settings were: 4l 2160x3840, 30fps, HEVC.
