Same color renders differently on different screens

I have a problem with the same color rendering differently on different screens. This happens with multiple devices (both Android and Apple). I am confused why this happens, anybody has any ideas?

The orange color should look the same but it appears dark red/brown on some devices.

This was covered recently.

Convert to PNG before upload I think was the outcome.

They are already in .png format :frowning:

I would say raise a support ticket for this.
