Anyone else have a DTEK50 model RHZ191LW ?

Hello, I'm not a member of this forum but I'm hoping one of you might be able to help me. I bought a DTEK50 just over a week ago. The box details give the model number as RJD211LW. However, when I put the IMEI number into an online checker, it gives the model number as RHZ191LW. I'm a bit confused. Can anyone throw any light on this? I can't seem to find any detail at all about this RHZ number apart from a mention on this forum pretty well exactly a year ago listing it amongst some new unknown device IDs. Anyone get the same thing come up for their DTEK50?

IMEI checkers are dodgy. I'd rather check the horse's mouth:
