(Contains spoilers for the KCD Epilogue)
Henry Kobyla is a Nobleman. As we all know, towards the end of the game; Sir Istvan Toth informs Henry of his real Father - Sir Radzig Kobyla.
This means that Henry is the illegitimate Noble son of Radzig. Illegitimate meaning born before marriage, therefore he is known as a bastard.
However, Henry is acknowledged and accepted by Radzig Kobyla as his Son, therefore, since Henry is the only Son of Sir Radzig Kobyla, makes Henry legitimate because there are no other heirs.
Also, during the siege of Talmberg when talking to the quartermaster, he will say:
“I see how it is, the young lordling is just checking on us.”
This means that Henry is publicly recognized as a Nobleman, the Son of Sir Radzig Kobyla.
Furthermore, towards the end of the game, Sir Hans Capon says to Henry:
“It’s much better for me, a Nobleman to befriend a Noble Bastard rather than a blacksmith’s boy.”
This clearly shows that Henry is recognized by the other Nobles as a Nobleman too.
Now, when Janek asks Henry how to be adressed and Henry says:
“Oh, come off it do I look like a Lord to you?” Is a joke. Besides, Henry clearly doesn’t want his friends to call him Sir, but rather the public. Also for example, Sir Hanush and Sir Radzig are friends and they only adress eachother without saying “Sir” occasionally.
There are many other examples but I wanted to make this post to re-enforce the fact that Henry is a Nobleman now and in future DLC’s such as The Amorous Adventures of Bold Sir Hans Capon, Henry should he adressed as being a Nobleman.
By the way everyone, this is my first post!
