Yes, I've replaced a number of PSU capacitors in 'Sony' soundbars - obviously it's NOT a Sony product, and is just bought in from China - because capacitors don't fail in 'real' Sony products as they fit higher quality ones than lesser manufacturers.
In fact I've got a Sony soundbar myself - I delivered a new one to a lady, and she asked me to take the old one and dispose of it for her. One quick capacitor later, and I disposed of it at my house
In fact, following your excellent link, if you check the original photos you can see that capacitor is domed, so most likely it's low ESR.
