Do I need to upgrade my Sonos soundbar?

I got my Sonos soundbar back in 2017 and it’s been great - never failed great sound

I’m thinking it’s time to upgrade the tv as that’s also the same age but wondering if there is any benefit in doing the same with my Soundbar

Would a never Sonos bar be better or should I stick with what I have?

Have included a pic - not sure what model it is?
