not due to your terminal settings that influence how strings printed by
Python or inside used terminal are shown?

Python 3.9.6 (default, Jul 16 2021, 00:00:00)
[GCC 11.1.1 20210531 (Red Hat 11.1.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> UL = '\033[4m'
>>> UL
'\x1b[4m'
>>> ENDC =  '\033[0m'
>>> ENDC
'\x1b[0m'

>>> s = UL + 'D' + ENDC
>>> s
'\x1b[4mD\x1b[0m'

>>> s = 'ABCDE'
>>> s = s.replace('D', UL + 'D' + ENDC)
>>> s
'ABC\x1b[4mD\x1b[0mE'

When I call  print(s) it even shows ABCD and D is underscored. But copying
the output to mail looses the underscore ...
