Is there a carrier name on retail-devices?

Hello members of XDA!

Yesterday, late in the evening, I flashed my Moto X XT052 back to stock. Because of my tiredness, I pasted some code in the terminal:

Code:

---

fastboot oem carrier config vzw

---

I set my carrier name to Verizon, by mistake. But the device itself is a retail device, with no branding or such stuff. So here comes my Question:
Is it possible, to erase the carrier name? Better: What is the default carrier name on retail devices, which are unbranded and habe no carrier? Do retail devices have a carrier name? If no, how can I get rid of my intellectual nonsense, I put in there?
In my tiredness, I forgot to check the setting of the carrier with

Code:

---

fastboot oem config carrier

---

This mistake of mine sucks, because in stock ROMs there will be whatever I described as carrier name added to the build version, and I don't know, if this could affect OTAs in the future. I'm back on CM12 right now, so it's not a big deal, but it's causing sleepless nights :)

So maybe, you people can help me out?

Kind regards
