Umm, pretty sure you never have been able to on Brave. You might be thinking of another browser used or something. But you can even see where this has been something people have requested from as far back as 2019:
Hi,
I’ve recently switched from Opera to Brave and I’m very impressed by the performance difference. One thing that does bother me though, is while the Non-Private New Tab is this beautiful background with Bookmark buttons and other statistics, the Private New Tab is this large wall of text saying that you’re in Private Mode.

And someone in 2022 hoping a flag they saw would allow for change, but it wasn’t.
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.
