I love the game but, this genre is not "oled friendly".
Just like the sims, age of empires...
As long as you display other things sometimes it's not a real issue, unless you only play that game.
OLED "burn-in" is not caused by a static image for hours, it's the accumulation of that static image over time.
So a game (or anything) with fixed UI does the same to the panel if it's displayed 100 hours straight as if it was displayed for 100 hours but for 2 hours on 50 days.
And with burn-in prevention systems it's less of an issue now with pixel-shifting and darkening of static elements.
I played many hours of Cities Skylines and Transport Fever 2 on my OLED TV (50+ hours each) and it does not have any signs of burn-in.
Also, many games have static UI elements, smaller but still static, like Zelda BOTW and TOTK, hearts and other UI stuff do not move, yet it's not an issue.
