When I worked for a bike importer and we had to take product photos for catalogs, we attended to these details, not out of a misplaced sense of style o rules, but to make labels or other features most clearly visible. This was well before digital photography, so it was an expensive slow process. Everything was oriented to the camera which was above the bike slightly shooting down. Rim labels were at the bottom, Tire labels usually near the top, cranks oriented so the brand showed out well under the lighting, and likewise everything else. Then lights were aimed so glare or reflections didn't obscure everything, and when all seemed right Polaroids were shot to make sure, before the actual photos were taken.
A constant internal debate was wheel quick releases, because these were the only brand ID for the hubs and were on the left (out of sight in the photo). We tried a few shots with at least the front QR reversed, but they never looked right, and we gave up on that. Besides that would be endless debate about nonsense like seatpost height and stem extension, and whether the pedals should be turned so the toe clips were up, or allowed to hang upside down as they normally would.
Taking studio shots with owners, ad men, art directors and mechanics all in the same room prepared you for a career as a marriage counselor. The only thing was the annual ritual of deciding on color schemes.
