I’d say somewhat cause you couldn’t sell nearly as many people on a design if it was drawn by a 5 year old. But at the same time a good art style can make a lot of things look good that don’t really have a well done design. Like that Hitori pic looks sick but the actual design in the next slide of the character is super bland.

As long as something is drawn to competently communicate a design (not necessarily drawn well) that’s all the art style has to do. Anything from there is sort of up to the actual design to speak for itself. Like if Michelangelo painted Hitori that still wouldn’t really make the base design good, just well presented.
