I think the potential issue depends mainly on how you do the press-check (I've seen some people do it like a two-handed, almost-full slide rack, almost to the point the ejector is about to kick in), and then second on the ammunition used. Seems .40 S&W, which I still shoot, has had more of a problem historically than most other calibers.
That said, setback typically occurs--if it's going to occur--when a bullet pushes against a feed ramp. In most normal circumstances (and if you are not pulling the cartridge mostly out of the chamber when doing a press-check), the bullet shouldn't encounter any nose-on resistance when moving slightly in the chamber. So I'd think the greatest risk of setback comes from chambering the round from the magazine, and that a true press-check shouldn't tend to add to the problem.
But, yeah. It's second nature to me to do a press-check almost every time I holster a pistol or sling a rifle. I say "almost" because if I need to do something like reposition the holster a bit on the belt, if all I do is unholster, lay the gun on a desk in front of me, position the holster, and then pick the gun back up (which has never left my sight), I'll skip it then.
Well I can tell you that when I did press check, it was just enough to confirm I had a bullet in the chamber. I used to do it fairly frequently, not so much now. With Glock's (which is what I almost always carry now), there is really not much of a need as I can still visually see a bullet in there by some smallish gap between the slide and the barrel. Or with the extractor slightly protruding.
As i mentioned before, now I regularly rotate my carry ammo. Either moving rounds around in the magazine once they've been "up top" or shooting the magazine. Which is probably a better thing to do as I can see how the ammo shoots to point of aim.
