Hi, thanks for the report. I can confirm.
Prior to 3.4, sculpt normals were updating after normal viewport update (zoom/orbit)
Raising the priority since this is a regression.

I suspect this is caused by 65900d88a8

This is actually not supposed to work at all. Dyntopo now respects face smoothing settings.

@JulienKaspar
We could add a "Smooth Shade All" button that would set all faces to smooth. Maybe a "Flat Shade All" button too. Internally I would just add sculpt support to the existing smooth/flat shade all operators.

I could also add back the concept of a smooth shading override. I actually kind of think a flat shading override would be more useful. It's not really useful to view flat faces you want to be flat in smoothing shading, but it is useful to view smooth faces in flat shading. At least it seems that way to me.

I actually kind of think a _flat_ shading override would be more useful. It's not really useful to view flat faces you _want_ to be flat in smoothing shading, but it _is_ useful to view smooth faces in flat shading. At least it seems that way to me.

I can confirm that the toggle is currently overriding the smooth/flat shading of the object, but only when switching to object mode.
That seems like a bug.

The intention is to get rid of the toggle all together.
If the object should be smooth/flat shaded, use the context menu in object mode.

@JosephEagar I agree that there could be a need for a toggle to override the smooth/flat shading while in sculpt mode. But if this get's added it shouldn't be specifically for Dyntopo.
That should be a setting in the "Options" panel among the "Display" toggles.
