Hi @Divya Rajasekar 

Refer KB: KB2686590 Theme option is not available on user preference 

Resolution

1) Check if "glide.ui.polaris.dark_themes_enabled" is set

--> glide.ui.polaris.dark_themes_enabled = true

https://www.servicenow.com/community/developer-forum/theme-option-not-showing-under-preferences/m-p/...

2) Compare with the out-of-the-box configuration, and check if custom theme has dark theme variant available. Creating a dark variant should resolve the issue.

* Out-of-box theme -- You can see a dark theme variant: 
/nav_to.do?uri=sys_ux_theme.do?sys_id=31bf91ae07203010e03948f78ad30095

--> You can refer to below KB article to Dark theme variant && refer to the out-of-the-box theme for reference.
KB1647718 - Applying Dark theme variant with custom configured theme

3) Check if only custom them is published in Theme Builder WHILE default Polaris is NOT published.
/now/theme-builder/manager

--> publish OOB Polaris theme to resolve the issue
