Rims that bend Inward
It all depends on who manufactures a wheel and how they manufacture it.
One piece cast wheels have the hoop (barrel) and the center as a part of a single casting. The shape is built into this casting. There is very little (if any) flexibility in this type of design.
Two piece cast wheels use one casting for the center and another casting or forging for the hoop (barrel). The shape of the wheel is in the center casting design and offset requirements (fitment) of the wheel. There is more flexibility with offset and backspacing with this type of design. There isn't a whole lot of flexibility in the center shape.
Two piece forged (billet) wheels use different center forging blanks to achieve different shapes. They also use forged hoops (barrels) A forging blank is chosen based on application and fitment requirements. There is a great deal of flexibility here in both center forgings and hoop forgings. It is rare that you could find any fitment that a two piece forged wheel would not work on.
Three piece forged (billet) wheels are very similar to their two piece counter part. The difference being they use a two piece hoop (barrel). One piece for the outer and one piece for the inner. These hoops are available in preset depths that can be mixed and matched to achieve a desired fitment. You can usually achieve the highest level of custom fitment with these three piece wheels.
You should also be aware that as you move down this list from one piece cast to three piece forged the wheels get more expensive. The increase in cost reflects both the higher quality product as well as the labor required to produce it.
Hope that helps.

What you describe is a fairly common design feature in cast aluminum wheels with fairly high offset, like those needed for fwd vehicles. The "look" depends on how the spokes and rims interface.
Be warned that this style of wheel is more easily curbed and chewed than designs keeping the spokes behind the rim plane...
The center caps on many aftermarket wheels bear the maker's name, which can help pin down where to buy something you've seen and liked...
