They should be able to get 4k@60 with the older docks. I have such an older monitor which works fine. It's just that the usb 3 ports work at 480 Mbps.

With USB->DP adapter yes. With a hub offering USB3 ports, mostly no. Once both lanes are in DP-alternate mode (needed for 4k@60), there's no bandwidth for USB3, only the separate wire for USB2. So here it depends how it is internally connected, and whether it can switch USB3 ports to USB2 or not. Many hubs can't do this.
