It looks like that the this receiver may come with the Broadcom 7444S chip which was used for the older Ultimo 4K receiver.
This implies that this receiver will not be able to play 4K files or IPTV streams coded in H.264 (mpeg4). 4K support will be limited to H.265 / HEVC.
It's OK if you only watch satellite but otherwise beware of this before buying this "new" receiver which basically is re-using older hardware.
