Color shifting when importing stills as reference in color

Hi everyone,
I work at an agency, and for color grading, I always aim to match the reference photo as closely as possible (usually taken on the same day as the video footage). However, I’m facing an issue: when I import the reference photo as stills into DaVinci Resolve, the colors shift. But when I open the same photo in Finder, the colors appear correct.
I’ve tried converting the color space of the photo to Rec. 709 Gamma 2.4, but the issue persists. I’ve searched online for solutions, but haven’t been able to find anything that works. I hope someone here can help!
I’m working with a Mac-based workflow.
