I reckon you'd need to be one of those 'super-tasters' to notice a difference. 
Yeah, unfortunately for me, my daughter IS a super-taster. Has been so since birth.

Plus, on medical advice she has to have a lot more salt than most people do and can tell me which one I've used (or rather, did, at "home" when we had several varieties) without seeing me put it on the food.
And yeah, Colorado and the Highlands have amazing water. I spent 20 years in far West Texas, and the city water was pumped in from lakes, heavily treated, and nasty. Had a friend who, before fracking ruined the water table, had a deep-water well. God, that was the best tasting water!!!! If you ever get to Glastonbury, the water out of that magic well is pretty amazing, too. Tasted a bit like copper to me, but the daughter said it didn't to her - but she loved it. Wonder what the trace element is in it that is so strong?
Water in Glasgow is nice, too. I can actually drink it straight from the tap. In San Diego the water, while technically "safe" had xyz parts per million of industrial solvent, jet fuel, etc.... and the chlorine would have knocked your socks off. It was also extremely "hard" water. I am just now setting up a tropical fish aquarium and did my first water chemistry test as the tank "cycles" before we get a fish for it. That's the first time I've ever seen the results for water that wasn't heavily akaline. Thought I'd done something wrong, then remembered that I'd been told the water is very "soft" here.
Sigh - fracking. I do remember the water in W. Texas got worse and worse over the years. (Thank you, oil companies!

). The last time I was there for any length of time if you went through the car wash they had signs up to be sure to dry your car immediately or the water would damage the paint.
I don't miss those days.
