Not sure about the QA55's, but they are likely to be the same as the QN55's shown here - so not a VA panel on the 55"

Apparently "US Q80A = ADS (except 50, 85'') EU Q80A = VA" (from https://www.rtings.com/tv/discussions/j8_279MBwhLhbhzL/panel-type-65-european-model and https://www.avforums.com/threads/samsung-au9000-or-q80a.2381321/post-29709678), so I'm wondering whether NZ Q80A is like US or EU.

Well there's my theory out the window lol.....

As a side-note, I just bought a QA65QN90A yesterday. It blows my old 2014 Samsung 55" HD out of the water. I'm having fun working out all the features - the fact that I can use the TV remote for basic Sky functions such as powering on and changing channels blows my mind....
