I think the old 4 port usb-c macbook pros were similar, two usb-c ports were better for charging and supported thunderbolt, while the other two were non-thunderbolt and not optimized for charging. No visual markings.
It's interesting because the new studio display has 4 usb-c ports and 2 support thunderbolt, but they do indicate which ports are thunderbolt above the port.
