I noticed that too watching the game last night.
You can definitely see the change from 2019 to 2020.

As an aside though.... While I typically loathe the Cowboys, the media obsessing over them, and the oversaturation of primetime or nationally televised games they play a year.... Every uniform combination OTHER than their typical combo are the best looking uniforms in the league. I love the dark navy blue, silver, and white. It's a shame they insist on those light blue/metallic pants and non matching blue on the numbers for 75% of their games.
