How will 16:9 content look on the Nova?

I’m interested in the Nova, have an RP5 currently. I do plan to play a lot of gamenative on it and some switch.

How will 16:9 games look on that 4:3 screen? Massive black bars top and bottom? Or not too bad? Considering the black one to “hide” them/make the bars look like a continuation of the bezel.
