With Preview for Developers enabled, I'm on Cyan.With Preview for Developers disabled, I'm on Denim.

I've checked "Extras+info" a few times, by toggling "Preview for Developers" on and off, and I'm told to be on Denim ONLY when it's off.

Lumia 1020, Finland CV, with all updates applied via "Preview for Developers".

Is it also happening for you?

Its some known bug, I'm not sure if its intentional or anything - probably not

Yeah it's happening for everyone .. I remember that Daniel Rubino said before that if we wanna know the REAL latest OS on the phone with it's features we need toggle off PFD and see Extras+Info.

I think it is normal. I have it too on my 820 with Cyan.
Once I disabled the developer preview, I was on Denim.
I think it is because the developer preview is a "beta" of the Denim release. Disabling the developer preview, you aren't back on Cyan but have still the developer preview installed until the official Denim is released on your device.
