I honestly find this so frustrating!
Example: I go to GitHub, the page loads and since I have a dark theme set as my browser/ OS preference the GitHub page fetches a dark theme icon (in this case the icon is all white) but when I bookmark GitHub I'm served the original icon (black with white outline) and not the icon in the tab! Why?
Another website is the WebAlmanac, the icon in the tab and the icon on the bookmark are different!
