Could you give some specific examples of such usage? Some product in a technology field where there are "pro" and "non-pro" versions of the same product line, with the pro/non-pro distinctions as you define it.
Camera's. My pro level gear has features and options not on non-pro.
Physicals: nikon (its what I know best) puts more metal alloy into the construction. Makes them more rigid in construction. Also adds weight which a casual consumer may not want. Gets me a body or lens not as "disposable" as the consumers. I have some gear it is more cost effective even at a few hundreds to send in for PM/rebuild as cost of new too high. Vice some consumer options where the savings probably not there to do this.
AF-on button comes next to the ae lock button on the pro bodies' upper right corner area back of camera. Non pro lacks this nice feature. This button replaces the usual half button shutter release press to focus. After some time on a d700 (although entry, its still classed as pro) I am missing it on my non pro d750. As I have to reprogram menus to get AE lock to do this. Which means I lose AE lock on the fly.
Menu's I get more refined options on pro bodies. I have side by sided my non pro body with my high end consumer (but not pro) body and if menu's common I can have less granularity in the menu. Or its missing from the non pro body. I know in case of missing menu items its not removed...I know its on Nikon's later pro bodies after mine still.
Glass wise the most apparent pro feature is speed. F 1.4 primes are "pro" lens' even if not called as such. Some cheap 3rd party options to complicate this (some good by some accounts...knockoffs aren't always a bad thing) ...I am just going off what canon/Nikon/etc would say is their pro line. Zoom wise a hallmark of pro zooms has been constant F 2.8. Consumer zooms are not constant aperture. Exceptions include Nikon's f4 constant higher end consumer zooms, which can get the term of prosumer to complicate things. Wide open aperture at say 80mm will be different than wide open at 200 on a 80-200 zoom, lens decides this not the shooter. They are also not near 2.8.
Software: One I have been playing with a lot is parallels. It now has a pro version. Adds some nice features like network control. I can have a VM have a deliberately broken network connection. Useful to to test what an app dependent on the internet does when the network is iffy or slow. Non pro lacks this feature.
I in my desire to lose adobe as a post procession option have been giving DxO a go. Has a standard version and elite version. Guess they wanted to be different and not use pro. Site if you go there has the usual compare screen. Loads of features in the elite aren't in standard.
DxO is doing well in the side by side trials. If only apple didn't put a bullet in apertures head to make me do this. Which is another example. Apple in killing aperture tried to bring some of its "pro" features to the crap they have in OS now. They failed here. there was a reason we bought aperture. there was a reason why with its death many did not say cool...I get it for free basically in the stuff they gave a consolation prize. We said wth is this crap and sent our money elsewhere.
All this not bad thing though. Not an elitist if it comes off like that. have a need, you pay for it. Don't need it, don't pay for it. I have mixed pro and non pro stuff in software and camera's. If it gets the job done its all good.
Thing is....in the above when they say pro...they offer substantial reasons why its called pro. Reasons that aren't cosmetic.
