Could you provide the file ? Or a small version ?
Could it be a cache problem ? Did you try to clear it ?
Yes, cyans are impossible. There is a certain glowing cyan that Bridge (just as sRGB) cannot display.
I have had 2 images that I could not at all show as their "dumbing down into sRGB" completely destroyed them.
Purple is the other color sRGB/Bridge has problems with.
As noted, I created an sRGB conversion and compared it with the display of the image in Bridge. They matched, which proves that Bridge can only display sRGB. Which is ridiculous in 2019.
The particular image had a glowing cyan/purple color contrast and sRGB totally kills that image.
time to discard this poor color space on the web. sRGB was just created for those old computers who couldn't handle too much color information and those slow dial-up internet connections.
