I apologize for being somewhat critical of your otherwise fine review but you have not shown that the new sensor of the D7100 has any advantage due to not having a blur filter. In fact it may offer no advantage whatsoever.
The increase in sharpness of the D7100 over the D7000 may simply be due to the increase of pixels on the sensors.
To prove your assumptions you should also have included data from the same lenses used on a D5200, which has a similar sensor to the D7100, albeit with a blur filter.
My own somewhat uneducated guess would be that there is hardly any difference in sharpness between the D7100 and the D5200, and despite the price difference the D5200 sensor is actually superior when it comes to low light (your own tests).
