It just says…
- Bug fixes and performance enhancements.
…so quite possibly, but try it and see. It may depend on your TV make/model etc. or it might be your cable connection etc.
If the issues do persist however, then it maybe best to submit a Sonos system diagnostic report from within the Sonos App, note it’s reference and then contact/chat with Sonos Support Staff via this LINK and see what the Staff can perhaps suggest to resolve the matter.
