Yes, exactly.

That seems like an obvious corollary of the above... But yes, I think we could.

Not necessarily worse; just not better. Measuring and comparing outcomes across different populations is hard enough that it's hard to say more than "our outcomes are not clearly better than theirs".
> could we spend less and still get better outcomes?
This question is based on a premise which doesn't seem to be true, so probably no.
> How do you defined "more health care?"
Number of procedures per capita per year for various procedures is a reasonable measurement (where procedures can be MRIs, surgeries of various sorts, etc, etc). Usually people focus on the expensive end of this, by the way; having more physical checkups won't necessarily blow up your healthcare costs the way that more invasive cancer surgeries will.
