This is something that designers know and care about, and translates into "this box/plugin sounds good" vs "this box/plugin sounds bad" when hearing reviews or asking the dude at guitar center what to try out.

For example, if you were comparing AxeFX, Kemper, or Line6 Pod none of this would be on the labeling, but it's deeply tied to how they were designed.

For sure and I'd imagine these have to be designed with pretty high sampling rates internally to make sure they don't introduce too many artifacts and sampling issues.

But beyond musicians being able to hear what they like and don't like I don't think anybody understands what is going on. It's quite possible aliasing is part of "sounds digital" when a musician uses that as a pejorative... newer digital processing sounds less digital through better algorithms and likely things like better handling of aliasing.
