Option to Revert Back to "Old" Dark Mode?

I was in the process of taking another daily PT, when I noticed that the dark mode while testing was changed from the normally darker shade of blue, to a fully black interface. My eyes are pretty accustomed to the former while using a blue light filter, but they generally became strained fairly quickly from reading white text from a fully black background, which is what I experienced while testing.

Could we have the option of using the previous dark mode restored, or made available again through a toggle if this black interface is to be the new standard?
