That's not really true. It's not especially optimized for in the generally quoted low-distortion range, but higher frequency response generally comes along for the ride at least to an extent. Tweeters are probably often only like -20 dB all the way up at 30 kHz. That's significantly reduced response, but luckily dogs have very good hearing and it's not like people are going to notice if the inaudible part is very loud to compensate for poor speaker response. But probably most people are watching over streaming, and you'd be lucky to get 48 kHz sampling (meaning 24 kHz audio at the top end) that way. But 23-24 kHz is going to be inaudible to people too.

Consumer grade electronics cannot reproduce frequencies that high.
