Yeah some psu modifications seems exiting as the use of 100uF/400V instead of 220uF/250V caps.

Which mainly helps to reduce the psu oscillation sound.
As for the operation of the psu it makes not really a differences.
But if you use a scope you may see a better result, the curve is a bit better.
So yes. it's improve the psu a bit, but not really necessary.

But this is my thoughts about it, an other cap believer may think different.
