Same issue here. Two identical displays (Dell U2410), same color profile applied, (very) different colors. Anyone found a solution to this? I'm on a 2021 Macbook Pro 14" M1 Pro.

Same issue here what...?

I suspect it is hardware—try a different Dell U2410 to test and eliminate the monitor itself.

Try different cable(s)

Try different port connections
