If you aren't seeing any smudging or banding, it probably isn't
necessary. Honestly, the height difference isn't that great, in terms
of the head spacing.
Epson printers have used a number of adjusting for different paper
thickness over the years. Many earlier models just used mechanical
levers. Some newer models use software controlled adjustments, however,
driver selection can change more than head spacing, such as amount of
ink used, dot size, etc. Every paper has unique characteristics, which
is why each printer company specs their own papers (even if someone else
makes it for them), taking advantage of the characteristics of the
specific paper surface and qualities.
I find it is often just better to make some small sample prints and compare.
