slight color/sharpness difference between high res screenshot output and sequencer output??

I’m working on a scene and the render output from the high res screenshot give me the expected result.

When I render the same exact camera with the same exact post process settings, I get a slightly cooler, and overly sharpened result.

I’ve attached the two frames in question. Again the cooler result is the output from the sequencer.

Does anyone have any idea why there would be a difference in the outputs with the same settings?

Please disregard the black bars.

Thanks in advance,
