Wouldn't you notice that fairly suddenly everything's getting brighter because all the light/radiation is sucked back in?
I learned recently on [a video](https://youtu.be/a4vHwY0wMjs?t=246) that for very large black holes , we suspect there is no difference.
For smaller BH, the gravity gradient is higher and it would be detectable.
