I estimate that this should look good, but honestly, I never saw them sand 1 or 2 mm deep by the width of the tape along the entire length. Imagine if they have to make a building that detail would take a lot of time. If you tape the tape superficially without folds and putty on top with a spatula or trowel you will not notice the tape
They choose without discussion but a garage is not a building and if in a building after having done the ceilings they have to fix them all I imagine that nobody would do it as you indicate.
Now I tell you why, because of my sayings, in my house a plate was bad and it was framed, you know that the edge of the plates are thinner so that it is filled with tape and putty so when it is filled the plate is flush and the union would not be noticeable, if you put more putty and tape on the plate it shows (because that happened in my case) and what they did was sand until all the tape was removed
