Your .profile should be written to dot in ~/.bashrc if it's being run
by bash. E.g. something like:
test "$BASH_VERSION" && test -r ~/.bashrc && . ~/.bashrc
In the absence of this, you will not have the desired shell environment
if you ever use a login shell -- e.g. if you hit Ctrl-Alt-F2 and login
on a console, or if you ssh into the system.
If you never do either of these things, well, you're fine.

In a proper universe, the former would exec (chain-load) the latter.

Sounds atrocious.
If you ever feel bored, you could run this experiment, and see what
happens:
1) Put "umask 002" in your ~/.xsessionrc file.
2) Log out and back in.
3) Open an lxterminal.
4) Type "umask" and see what it's set to.
If my conclusions from the OP's post are correct, it will report 0022,
the Debian system default, totally ignoring your attempt to customize it.
Less invasively, a process tree showing the ancestry of a shell running
inside an lxterminal would be helpful. Something like this:
unicorn:~$ pstree -s $$
systemd───login───bash───startx───xinit───.xsession───rxvt───bash───pstree
That's for one of the rxvt's that's launched from my .xsession file;
for one that's launched from the FVWM menu, I have:
unicorn:~$ pstree -s $$
systemd───login───bash───startx───xinit───.xsession───fvwm2───rxvt───bash───pst+
