I have an old application which renders with the red and blue channels swapped. Is there a way I can use a color filter or display profiles or something else to fix this? I'm willing to use a solution that's either specific to the application or global to the system so long as it can be easily toggled.

    What application? I doubt this is fixable at OS-level; changing any aspect of the display profile would not be capable of literally swapping two input/output channels, afaik. It could possibly be done through a video 'effect', LUT etc, but idk how you would inject that to the app's output.

Depending on how often you need the application you could use OBS to capture the window and aplly a filter like the streamfx color filter to the image to fix it and then view the output in the preview window. This is pretty unpractical if you want to use the application a lot, but for using it seldomly this should work.
