i5 v i7

Can anyone upload the i5 and i7 comparision with these kind of chart ?

It should be the same screen in all of the SP3s, so I wouldn't expect to see any difference from what you've posted. That and it takes some fairly expensive equipment to perform that kind of measurement, so not many folks around here, if any, are likely to have something to test with.

It is indeed the exact same screen across all models of the SP3, so no difference other than manufacturing tolerances to be expected.
