From levels 1-4, proficiencies only affect 1/10 rolls. Once you hit 17th level, they're affecting as many as 3/10!Proficiencies do matter. Inspiration gives you advantage on an ability check, not an auto-success.

Unless the DM is denying non-proficient rolls, auto-succeeding proficient rolls, routinely using passive scores or otherwise deviating from the 'roll and add modifiers' scheme (all things which will affect inspiration usage as well), then proficiencies are very low impact, with the exception of characters who get significant skill use boosts.

Yeah, it is. +2 to your rolls actually only makes a difference to your success/failure against a static DC 2 times out of every 20 rolls (on average, naturally). The 2 times that it makes the difference between meeting the DC and not meeting the DC. Every other time, it was irrelevant. A bystander would not be able to tell whether or not you had that bonus.
That's different to how it affects your success chance - you need to know the DC, and your original bonus for that. But if I'm just rolling a d20 and trying to equal a 10, then a +2 bonus will only change the outcome 2 rolls out of every 20 (assuming a DC that originally requires a roll).
