After a disastrous delivery: The TV is not comparable to a Samsung. Mine sometimes doesn't switch on at all, or has to wait 2 minutes. The menu navigation on the TV is delayed and the picture only comes into focus after about 10 seconds. I'll be returning it as soon as I go on holiday for 4 weeks. No effort for nothing. Give it back, it's not going to be good.
Unfortunately, I was not satisfied with the appliance. I returned it after 7 days. After that I got a Sony TV, it's better so far. Maybe update the software?
Below you will find the distances between the floor and the bottom edge of the TV. This means that the 65" model would be very close. However, the soundbar should not cover the picture. Depending on how accurate the 58 mm specifications are.
