Sorry, your right I missed that. Then don’t bother with the angle test.
Infill % and infill pattern will greatly influence the outer texture of the model. Perhaps that what you may not have realized when you printed it the first time. It’s easy to overlook when one changes one of those parameters. In fact, conduct an experiment and change the infill pattern and in a separate test, change the infill angle. Then observe your results. Keep the top and bottom layers to 1 for a more exaggerated view. Also, consider experimenting with the print order from the default inner/outer to outer/inner. That too can have a dramatic affect because the exterior walls will be printed first forcing the interior inward.
