I've only noticed it with Auhagen structures.
They have two lines, one HO and the other is HO/TT. TT being 1/120 scale. These dual-scale structures are scaled at 1/100.
These undersized structures can be made to work in a forced perspective setting and they can also work if they are placed with smaller HO scale structures.
I haven't bought any US designed or manufactured structures in over 30 years so I'm not certain how their structures compare.
Other than Auhagen with their dual-scale offering, German and Austrian structures are true to scale.
Auhagen was located in the former East Germany and TT scale is still popular in that area and points east. Especially the former Soviet Union.
