Intel Skylake Gold 6154 CPU genuine or Engineering Sample? Intel Diagnostic tool passes but CPU-Z and HWInfo shows "ES"

I am testing a GPU Compute Server (ASUS ESC8000 G4) with 2 Intel Xeon Gold 6154 CPUs and I ran the newest version of the Intel Diagnostic Tool (IPDT, Version 4.1.4.36.W.MP) and the tool passes all tests and indicates that both are Genuine Intel CPUs. But CPU-Z and HWInfo show the CPUs are Engineering Samples ("ES"). What is going on? Should I rely on Intel's Diagnostic Tool or doubt the CPUs to be genuine production-grade products? All hardware diagnostic tools I tried (HWInfo, CPU-Z, IPDT, Task Manager show that all cores run at full spec capacity and I have not had any issues so far) but the CPU-Z and HWInfo page still makes me doubt...any ideas what is going on? I also noticed that the newest version of the Intel IPDT tool does not include the SPBC tool, could that be the reason? Where can I get the SPBC tool?
