If Quatix 7 Sapphire is almost the same watch as the Epix 2, what is the Quatix 7X ? Is it almost identical to Fenix 7X instead?

As per title. It just occurred to me that the Quatix 7X does not have the AMOLED display of the non-X version that made everyone think it was just a variation of the Epix Gen 2 mostly. It indeed has a MIP display, like the Fenix line. So what's a Quatix 7X like in terms of firmware?
