The nature of precast panels over such a large expanse means that even with the finer grain of the brick panels/grout lines, any sort of misalignment of the panel is really visually highlighted. I'm a bit worried about the blank wall now too. This is an example of something that would not be a problem with traditionally laid face brick.
The elevations that feature the "grid" of brick around the windows and inset balconies should be much more successful, as the shorter spans of "brick" (smaller precast panel sizes) will visually downplay any slight misalignment and other defects.
The colour of the brick changes so much depending on the light. These are all from the same time.
Windows! Hard to tell the colour of the frames. Charcoal? Maybe a raw umber sort of grey brown? Definitely not silver.
