It is an LG panel
and they are very accurate compared to reference monitors when calibrated, just a question of what release year this was originally, seems to be either 2021 or 2022 model.If it were $2200 or less, this would be a solid deal, but not this price. Hopefully Philips OLED TV stock becomes the norm in AU because they produce a very compelling product.
EDIT: was confusing it with Panasonic OLED TV models, disregard the colour reproduction statements. Seems to be a 2022 model.
