Revamped Incognito New Tab Page

So in the last update we got a new flag called “Revamped Incognito New Tab Page”. I was excited cus I was hoping it would fix the ridiculous purple on black forced theme in private mode. Sadly…No only did it not fix this I cannot find any information on what this is supposed to do.
Please bring back the " Incognito brand consistency flag" or fix the Private browsing theme to something sensible. Perhaps this is only an issue on MacOS.

FYI - Looks to be the same purple theme in Win10… which I don’t care for either! Just reading articles on the web, it seems it is only available in Chrome Canary for Android at this time…
