SB6141 for 200mbps download? - Time Warner Internet

This question is about "SB6141 for 200mbps download?", with Time Warner Cable internet and apps. Spectrum rated this modem for 100mbps only, but when I run speed test I always get 200+mbps after I just upgraded to 200mpbs internet. Do I need to change the modem? It seems to be working fine. What does "rated" mean anyway?

By the way the spec says it can handle 343 Mbps download.
