Yeah probably. Sometimes I'll tune into a game and it almost seems washed out, like the colors don't pop out because everything is so overwhelmingly bright.
But also there's bigger issues with the game itself that cause the games to feel more bland and like they carry less weight. And on top of that, when Curry and LeBron retire I think the NBA will continue to see declining viewership. The current superstars don't seem to have the same star power.
