If you don't require swivel bracket, can considering getting from courts online store.

Mi TV P1 55" ($719) + Fixed wall mount installation ($63)
Delivery should be another ~$10.
All in should be just under $800, for 55 P1 and fixed bracket installation.
However, stocks are very limited (left 4 sets as of this posting).
3yrs onsite warranty from official Xiaomi SG is better than the 2yr carry-in warranty by PI resellers.
