TV and Movie artwork on Catalina vs. Apple TV

I finally took the plunge and upgraded to Catalina following the 10.15.6 release. So far so good operationally but I’m flummoxed by one particular change. In the new TV app, both movie and TV artwork now has a 16x9 horizontal aspect ratio. On my Apple TV 4K, which also updated recently, the movie artwork is still vertical 2x3 and the TV artwork is square. Why did they change it? Is there any way to get Apple TV to work well with the new artwork? On Catalina, the old artwork is ugly, while on Apple TV, the new artwork is ugly. Any suggestions?
