It depends how D&O test

To double 24MP sensor resolution in isolation requires 96MP - unless technology improves by the time 96 MP becomes possible in 35mm format cameras.

Many sources suggest D800 resolution measured in isolation is about twice that of a gold lens tested in isolation. If this is right going from 12MP to 36MP improves file resolution from a good lens by about 30%, and by less going from 24 to 36MP.

Whether you rely only on a 1000 to 1 contrast chart test results is personal choice. Subjects with 1000 to 1 contrast in the real world about as rare as hens back teeth.

1000 to 1 contrast targets do not measure the ability of more MP to better record subtle changes in colour, texture or exposure in landscapes, portraits and any subject containing lots of fine detail.

Many problems turn out to be a lack of intimate knowledge of complex modern camera equipment.
