Thank for your efforts to help me.  This time I used the exact code snippet you wrote, but the results for inline math is still not what I would like to have since I do see a clear difference in the limits placement. Please see this image where I have tried to make more clear what I really want to achieve and what the code gives me:  https://i.imgur.com/AEfHxBh.png

 

It might be a font issue, since examining the context and pdflatex output files,  I see differences in fonts, alghough the actual glyphs look pretty much the same. I don't really know.
