I admit that my first thought was "if anyone starts posting cat photos, I'm leaving."
But the samples do serve a purpose, of adding to the evidence that:
(a) 20MP gives enough definition, or indeed more than enough, for a great many purposes,
(b) modern lens designs can keep up with that 20MP of definition even in a format as small as 16mm diagonal with 2.4 micron pixel pitch, and
(c) the previous item can be true even with a zoom lens from an upstart mass-producing consumer products conglomerate like Samsung, rather than only from century-old German makers dedicated to high end photography and optics. (Google Translate tells me that these samples are mostly or entirely with the NX mini zoom lens, not with the 9mm wide-angle prime.)
The same sensor might be junk for a wide angle expansive landscape though.
I am curious as to what problems you anticipate when this 16mm diagonal sensor is used for a landscape: it is not as if the massively blurry backgrounds or high speed performance beloved of the big-sensor, big-aperture enthusiasts are of much importance in landscape photography, or that a camera which gives good color accuracy in these samples is likely to change to giving poor color accuracy for landscapes. If you are looking for a "yes but what about ..." way of diminishing the significance of these examples, why not try "... a black and a white cat fighting furiously in a mixture of bright light and deep shadows".
