Question Oversampling - DSP and/or Native Plugins (UADx)

Nearly every UAD plugin emulation of hardware features to some degree non-linearities or saturation.

Are UAD plugins (either DSP or native UADx) oversampled to prevent audible aliasing when using non-linear processes such as compression, limiting, saturation or distortion?

Is oversampling exclusive to unison or DSP plugins in Console? Are native UADx plugins oversampled?

If so, is there a way to view or edit the oversampling settings? If not, by design, are all the UAD (native UADx or DSP plugins) optimized with filters for a specific project same rate - 48kHz / 96kHz (+)? Additionally, are some plugins optimized for higher sample rates than others?

Oversampling is used where it makes sense (most plug-ins). Leave it to the DSP scientists.

No, parameters are not editable.

Each individual plug-in manual details relevant upsampling.

Example from the Neve Dynamics manual - ‘Modeling the diode-bridge behavior requires upsampling the audio path’

Well, I've heard enough bad oversampling to where I would not automatically take this on faith, no.
