All black mail areas?

[M0710NM4N]

So my main Accounts menu is a nice dark black but then when you go into view the list of emails it's a grey area as the picture shows... possible to make this black with just a thin white line seperating the emails?

Hi,

The greyed area indicates that this message is ready. Please mark one message as unread and the fill will become pure black. It's an intended behavior and can't be altered.

Regards,
