Would you believe Apple set some of those records based on Displaymate's little caveat that says: "
Note that Numerical Performance Differences that are Visually Indistinguishable are considered Matched and Tied Performance Records."? It says so right underneath the title where you copied the stats.
Would you believe if you take the Note 10 review and compare the records some of the data will show the iPhone doesn't actually hold those records?

I removed the records for the Note 10 that weren't relevant to the discussion. I did include the link if you're interested. Red bold indicates a record that really isn't a record. The blue bold is separate because I don't know how the peak brightness was measured. Both could hold a record brightness tied to specific criteria.
I point this out to reiterate trying to parse contribution levels is nothing more than folly. Apple and Samsung worked together to produce a great screen. Nothing on Displaymate's site is going to support anything other than that conclusion.
