A:Answer I bought this TV about a month ago. So far, I like it - there is a bit of a glare though just as an FYI..... according to the following Samsung link, it does appear this TV would support AirPlay2; I haven't actually tried it but when I go into "settings- general-Apple Airplay settings" it does show "Airplay on" , and Airplay version 25.06 (if that helps any) .....

Not familiar with Bose LIfestyle so not sure about that part of your question; but just so you know, the TV does NOT have any RCA ports ... it has 3 HDMI, 1 HDMI ARC, 2 USB, 1 ANT, and 1 digital optical port ..... we have an old DVD player - in order to hook it up, I had to buy a RCA-HDMI converter box (less than $10) in order to connect DVD player and it works fine.....
