New info, another person (that I would trust way more than me ) claims it's around 800P

I also find roughly a 4/3 ratio for both vertical and horizontal resolution which is exactly 810p.
A very long vertical edge can be found in the first image between the window and the book shelf. For horizontal resolution it's more tricky but we can thanks the FXAA naughty artefacting for giving us several long horizontal edges on the white truck here:

We can safely presume the native resolution (of gameplay-ish scenes) is approximately 800p.
But it's maybe exactly 810p!! After the Titanfall 793p resolution everything is possible!
