Classic theme for new teams

Hi.  I opened Teams Classic recently and it asked me to switch to new Teams.  So I did.  I didn't like the appearance, so I checked theme config.  I saw "Classic" so I was happy to see I could have it back the way it was.  I chose that, and the primary interface looked perfect.

But then I joined a meeting, and had a God-awful bright white meeting window open.  In Teams classic, my main interface was light grey with a blue bar at top while meetings were black windows.  If I choose dark theme to get the black meetings back, now my main interface is black.  UGH.  Is there any way to have the classic theme actually act like Teams classic? 

I prefer this look:

Thanks!
