Replace the titlebar colour into black. White titlebar is distracting to CLI contents.
The current white titlebar (when not using the optional theme color) is really distracting and just looks out-of-place on CLI.
I suggest that the console window should be like this: https://imgur.com/a/UQZS9
This is Hyper, a 3rd-party terminal app. An example of modern looking CLI that I think Windows deserve to have out-of-the-box. It is clean and way more focused to the CLI itself rather than the GUI chrome.
