Viewing angles (left/right/up/down)

Dear Picade owners,

I’m thinking about building an Arcade cocktail table from some of the Picade ingredients. Especially the 8" IPS display is nice - but I couldn’t find any review etc. of its viewing angles.

Spec sheet says 170 degrees, but this is most likely only from left to right (?). What is your opinion about the image quality when looking from top or bottom of the screen?
