Yes I did have that feeling. The first two hours I thought I would keep it over the standard glass, but after two days I ended up finding it more annoying than the standard glass.
There is a loss in sharpness and in color saturation.
The screen becomes unreadable at the wrong angle to a bright light source, because it becomes a surface of white shine. Even at slight angles, it causes the contrast to reduce. This turned out to be at least as bothering to me as the standard glass glare. This picture exemplifies why I don’t find it that great:

Even without the bright spots, you often have some amount of that shine across some part of the screen, and highlights in the bezels.
We‘ll just have to agree to having very different experiences, then. To me, the screen of my 12,9“ M1 Pro that I have yet to sell looks broken now as I am used to the serene nano experience.
