LG 55UA73006LA (2025 — webOS 10)
Hardware profile and low-level diagnostic data gathered from a root shell on an
LG 55UA73006LA, a 55-inch 4K LCD sold in Latin America, running webOS 10.3.1
(LG's webOS 25).
It sits on the same Realtek K25 silicon as the NU80; what differs is
the model, the browser region (a DVB board rather than ATSC) and the Wi-Fi part.
