iPhone 17 Pro Max Exposure Change After Exporting As sRGB

I upgraded from iPhone 14 Pro Max to 17 Pro Max. For some reason when I put my photos taken with the new iPhone through Lightroom (mobile version) to export them as sRGB for socials they come out much darker in exposure. This happens to all of the photos. I tried again my old photos taken with the 14 Pro Max and I don't have this issue. How do I fix this and what is going on? This is driving me insane.

Thank you very much!
