Screengrabs are washed out compared tot he video output

[Color09]

I' trying to get some 3840x2160 screengrabs of Joker, but they keep coming out washed out like this: [url]https://imgur.com/a/hhtAs1l[/url]. But when I use the Mac's screenshot feature (lower resolution unfortunately) it's color accurate: [url]https://imgur.com/a/q543nnR[/url] Is there anything I can do to modify the screengrab output?
