Its a possibility on Lemmy
The lemmy UI hides it, just like the Boost UI. What people do is they go to lemvotes.org and paste the url to the comment or post to see the up- and downvotes.
What lemmy has, that I'm uncertain if Boost has too, is a convenient way to copy the "true link" from the poster or commenters instance.
On Lemmy you copy the multi coloured star link and paste into lemvotes.org
