Flat panel displays are a rapidly moving target with many options. 
How do you know if the one you chose is representative of what home 
viewers will see?

This year is introducing HDR into flat panel displays ("LED" LCDs 
become super-bright and OLEDs become a little brighter), which will 
cause new issues.  We are also seeing support for P3 or Rec.709 
mapped into a Rec. 2020 space.
