What have we gained in 7 years? (picture)

Here is a full size landscape picture I took in 2009 with an antediluvian camera (the E-P1) and and an ante-antediluvian lens (4/3 Oly 14-54 mm).

When I saw the file at screen and 100% (pixel peep), I asked myself : what have we really gained in 7 years apart a bit of resolution, DR, and noise at high ISO (yes, DXO numbers)? Is it really significant?

This is a open question, I'm interested to know what do you think?

PP Note : ORF developed in LR6, exported as TIFF, lightly sharpened in Photoshop (Nik Sharpener Pro 3) and the sky was post-processed with Dfine 2.
