I have a long standing gripe with Samsung because they don't make it clear what type of panel tech they use. I think all their TVs are VA, but the only way to know is if they list either the viewing angle (VA is 176) or the static contrast ratio (VA is 4000).
Sadly, they choose not to.
So the only way for you to tell is to see it in the store and manually check the viewing angle. Look at it from as steep an angle as possible and see if the image looks normal. If it does, it is either VA or IPS; and because Samsung doesn't make IPS and the only other screen tech they have is PLS (only used on one monitor, and it's not that good), you'll have your answer.
