They claim to have a somewhat well spec’d panel (at least superficially):

Telly is a 55” 4K HDR smart TV with a built-in 6-driver soundbar and Smart Screen. The dimensions of Telly are 48” width x 41” height x 3.5” depth. Telly ships with 2 leg stands that are 44” apart. If you want to wall mount Telly, you can use a standard 400 x 400 vesa mount that supports approx 65 lbs.

Of course no details on what they mean by HDR or even what technology is used by the panel. :)
