What I would do if asking a question like that is to include links to the data sheets.
That makes it easier for members to easily get the information to review to help in your quest.

Both OP amp datasheets don't show the internal circuit diagram or at least a simplified schematic as to find on page 9 under
https://www.analog.com/media/en/technical-documentation/data-sheets/ad817.pdf
I note also the absence of the residual distortion curvature as to find in post #2 under
https://www.diyaudio.com/community/...st-possible-thd-n-really-the-best-way.367692/
But this diagram isn't publish in general unfortunately.
Thus it is necessary to make own investigations (listening tests, various measurements) for individual applications (such as line-amp, RIAA amp, I/U converter, front-end for power amp like Alexander amp or active crossover networks) for finding out the sonic character.
