(EDITED for punctuation; the name of the flag needed the dash)
Maybe I found something which works within Google Chrome, the idea found through an internet search.
Look for Custom-drawn Windows 10 Titlebar, and set this to Enable.
Incognito mode shows very dark gray upper bar; dark gray active tab, and inactive tabs are nearly but not as dark as the main upper bar dark gray. The icons and the text and the icon, text, background contrast all good enough that text and icons are easy to see. The contrast between active and inactive tab "colors" is strong enough that the active tab looks significantly bright compared to inactive tabs. Address bar/field is just slightly lighter than the active tab, and the text in the field is white, making for good enough contrast for person to read what's in the field.
Regular mode looks almost the way it did before enabling this flag.
Making use of this flag, Custom drawn Windows 10 Titlebar, seems to be the right way to make the browser details easier to see and faster for me, the user, to interpret.
I forgot exactly what my keywordings was when I did the web search.... I think the search lead me to a couple of extensions in the web store for google chrome, and part of the discussion described this flag specifically and how to find it.
