I tested the code again. Using Gmail SMTP server produces correct results,
using server smtp.seznam.cz leads to a problem (I should mention here, that
Seznam is the largest free mail provider in the Czech Republic). Here are the
differences on receiving side.

As you can see, Seznam is adding a lot of headers into mail's body. Anyway,
making utf-8 subject manually like this:
base64Subject = base64.b64encode(subject.encode('utf-8')).decode()
encodedSubject = '=?UTF-8?B?{0}?='.format(base64Subject)
message.add_header('Subject',encodedSubject)
works correctly for both SMTP servers. So there must be a difference...
