You're right. They have yet to confirm a breeding population, but sightings have gone from nonexistent 20 years ago, to 15 a year in populated areas and have been confirmed to be multiple bears. I'd say 10-15 yearly sightings of confirmed multiple bears in populated areas, constitutes a semi-permanent (I specifically didn't say permanent) population. That's to mention that the Game and Fish really isn't actively monitoring them and there's a lot of open space in area. Heck, even the SD Game and Fish has active warnings and instructions for what to do in case of the black bear sighting. Compare to ND that might have one sighting every two years.

Former North Dakota resident here. Bears are typically found in Forests and Mountains. States like ND are flat prairies and don't have the shelter they are used to, and are almost entirely farm/ranch land so don't have the food they are looking for. Yes, you might get one wander in, but its naturally pushed back and not a permanent population. It's the same with many of the other plains states. The one outlier I am suspicious of is Colorado. They don't have as many forests and foot lands leading up the mountains as other mountainous states, but it seems like at least a decent habitat that could house a permanent population.

The number of bears is South Dakota is much too high, but the Black Hills Nations Forest does have a semi-permanent black bear population in recent years.

Modern sets from reputable brands have all but gotten rid of burn in. If you have logo detection on, it will find static pixels in the display and dim them so they won't burn in. So far it seems to work on static TV logos in the corner and UI's like video games.
