In terms of size so, for movies and games so, for work No!

1) The most important point: A slight yellow tinge in white / gray colors
This is very much clear if another monitor is wrong. KO criterion for me, because the color reproduction is clearly falsified.

2) Vertical stripes
They are more likely to recognize solid colors, but came often enough before.

3) The frame seems to be fairly inexpensive.
4) The inner frame reflects the image on the outer edges again.

On the subject of PWM Flickering:
Unless one comes down approximately below 40 brightness he does not flicker, then oh so.
