No. Please see my earlier comment:
"Since I am still using a 2019 MacBook Pro I am unable to verify these claims, hence the post. I am looking for user reports. How does "No To Notch" work in real life? Issues?"
Not sure if my image was helpful. I know it compares the look to the 2018 model instead of the 2019 but maybe if you look at the picture and your 2019 from a similar angle you can compare the bezels.
With Mini-LED screens, black is truly black and looks exactly the same as if the display was powered off. So you can't see the difference between the part of the blacked out area that is notch and the part that is disabled screen space unless you get a lot of light shining on it. So it might as well be a real bezel at that point. I think you won't find the notch so bad once you have your purchase in hand but I can appreciate the need to have a plan B in case you find you can't stand it.
The app works by simply changing resolution. It is still handy if you want to go back and forth between notch and no notch quickly, but you can also just change the resolution yourself in the display settings, as DFBwin shared. The different resolution still seems to line up the physical pixels with software pixels so it's not blurred/filtered like you normally see with non-native resolutions. The overall look is what you'd expect the system to look like if Apple had not built it with a notch in the first place. The only issue I've noticed is that the resolution change seems to lose a few rows of pixels on the BOTTOM for some reason but it's a negligible amount.
It should be noted that a similar effect is normally done, with no third-party apps or changes to the default settings, if you switch an app to full screen. In that case though it's not a resolution change so you can still move your cursor up to the blackened area, and then menu bar content appears there. The resolution change we are talking about completely stops using the blackened area at all and makes the interface work like it does on a no-notch display.
I'd be happy to answer any other questions you have to help you. I could even measure the effective bezels if you want to compare that to your 2019 model. I have been in this situation myself with purchases and I can appreciate the need to have no surprises at all. You may want to have a look at how it works at an Apple Store. If that isn't practical maybe you could tell me what you'd try if you had the device in front of you and I could try to make a simple video for you showing the same thing.
Sorry people are being mean to you. Not sure what is up with this place.
