Comparing older 2014/15 24 mpx sensors to latest/greatest wrt IQ + DR?

This F.F. Sony a7R2 owner is only marginally aware of the Image Quality (IQ) (inc Dynamic Range (DR) of the APS-C 24 mpx sensors over the past 5+ years.

A possible misconception of mine is that in terms of "raw IQ", Sony has made only minor to moderate improvements in their APS-C sensors.

Ignoring usability issues such as screens, IBIS, menus, AF, etc ... and assuming a very high quality prime lens and MTF software of the "system" of sensor + lens:

Comparing the "raw IQ" of a very recent 2019 a6600 to a 5+ year old 2014 a6000, would the IQ (inc DR) difference be ...

  1. dramatic and obvious to a beginning point-n-shoot'er
  2. significant
  3. somewhat better
  4. between "somewhat better" and "marginally better"
  5. marginally better if you know what to look for in a 16" x 20" print
  6. no difference

My less-than-informed guess is that #4 applies.

I suppose the DR values from Bill Claff's "Photons to Photos" might apply for DR. Those are essentially the same for the a6000 and a6600 covering 5 years.

Is there an "apples and apples" equivalent to DR for resolution using Raws with little or no in-body "improvements" like sharpening? RawDigger?
