This may have been covered already, but are you creating a positive environment for the people around you? I honestly can't imagine anyone in a management position that would be ok with what you are doing.
Doesn't matter how much they like you and your nekkid posters, and how great of an employee you are, you are a massive liability. All it takes is one disgruntled employee to make a complaint to the labour board or file a lawsuit and they are ******. Same thing with a future recommendation, would you recommend an amazing employee to someone that has a very good chance of getting that company sued?
You say that you do not want to put on a fake persona for people, try to imagine it another way. I don't want to wear pants. If I go on a Zoom call in my undies, things will not end well. There are certain societal norms that we all have to abide by in the workplace, such as pants and no sexy time posters. Reminds me of the Chappelle skit, when keeping it real goes wrong
The only one in upper management who knows sent me a related present, then I found out he was a hidden weeb lol
Change happens slowly overtime. Also I know many ppl who don't wear pants on Zoom meetings lol
Client facing meetings are a different story.
Once again, need (or should) consider the environment you're creating around you.
Of course, hence why I'm sitting in a chat work group all day with people throwing really controversial **** that sometimes leads to heated arguments lol. There are women in here too. And I know we're friends because somebody will scream "LETS GAME" at 4:45PM, then get told to shut the **** up because it's not 5PM yet, and there's a full house with fun after.
....except for the one guy who wants to keep playing but has screaming kids in the background lol
