In Illinois where I'm currently stuck, the law says that concealed is "51% or more" is concealed. So in the photo with the OWB holster, in Illinois you would still be legally concealed because at least 51% of the gun is concealed.
One thing I need to explore with a lawyer is how the law treats the firearm and the holster. In my layman mind, your photo of the OWB carrying shows you to have the firearm 100% concealed because I can't see the gun. I can only see the holster. I'm pretty sure that it's not illegal in any state to have a holster on your belt because it's a piece of leather (or whatever it's made of). You only run into an issue legally if there's a gun in the holster.
Great point, and it’s worth discussing the distinction.
Way back in the early 1980s when was an LEO in South Dakota, the laws regarding concealed carry were very restrictive. Permits for concealed carry were cheap and easy to get (and they still are) and that may well have been part of the issue with having very little tolerance for even partially concealed carry.
For example, if you were out hunting and had a pistol along for a backup, coup de gras, etc, and the handgun itself was covered by your jacket with just the holster showing, it was considered concealed. In effect if any part of the handgun (not including the parts covered by the holster) was concealed, it was considered to be concealed.
Similarly, in many states you can have a handgun “in plain sight” inside a vehicle and it is still considered open carry. In South Dakota, if the handgun was in the vehicle, un-cased and within reach the driver it was considered concealed, even if it was in plain sight on top of the dash. (Please note I can’t speak to current SD law.)

In other states, partially exposing a weapon or a holster is considered to be unconcealed, and that can be a real problem when a state or jurisdiction allows permitted concealed carry but does not allow open carry. The reason some states or jurisdictions do that is because displaying a gun can make some people nervous.

I am however not discussing the legal side of concealed carry but rather whether the people you are interacting with in public will be able to easily detect you are armed. Printing under a shirt is one thing. Having a holster exposed is another. Most people won’t notice someone printing unless it’s egregious, like a handgun clearly printing under a tight spandex tee shirt. Most people will however notice a holster sticking out under a shirt.
Personally, I’m in the “concealed means concealed” camp where no one on the general public should know you are armed.
