I just say I'm "mostly paleo" and that can cover a lot of territory.

I do kind of feel like people who insist they're paleo and eat cheese, yogurt and dairy products are stretching the label a bit. I'd call them "mostly paleo".

But overall, it isn't that important. I guess I'd be pretty offended if someone who just eliminated gluten and ate a bunch of GF substitute foods called themselves paleo. If you're eat a lot of foods that have more than a few ingredients, then that doesn't strike me as being consistent with a paleo diet.

Getting hung up over labels isn't too helpful, although if someone tells me they eat a paleo diet, I'm going to assume they don't eat dairy.
