U2725QE, two, share the same color profiles in Dell Color Management app, is that expected?

I have two U2725QE monitors setup within last week. After playing with Dell Display and Peripheral Manager and encountered some weird stuffs (like inconsistent UI options across two monitors, but later re-aligned after several factory resets and option manipulations), and then I notice significant color differences between the two (after factory reset).

Then I installed Dell Color Management. I think the factory color profiles should be different on different devices, but the reality is the opposite, the color profiles of those two are exactly the same:

Is the factory color profiles of one of the two monitors overridden? And that doesn't seem to be expected right? If that could happen by design, how do I restore factory color profiles?

Another proof for this is that, I noticed color profile duplicates in Windows display settings of one monitor (same names, but suffixed by numbers).
