Есть ли что-то недостающее, что можно исправить для внешнего вида

This is a fault in the DVB-S2X driver, the DVB-C/T2 tuner is not affected. Since it was VU's very first DVB-S2X tuner, a few things were buggy. The box was released over 2 years ago and nothing has happened yet. I think it is realistic to say that this problem will never be fixed probably because the tuner hardware simply doesn't return these values... Hardware will never be replaced now under some kind of warranty... Live with it or buy another box if this function is so important to you...

Because they can't.. The fault is in the tuners design. It can't be fixed by programming.. Only solution would be to call-in every VU+Zero 4K sold and change the tuner. Obviously this is never going to happen. Maybe - just maybe - this was the reason why they were sold so cheap..
I own 5 of these devices and they work exceptionally well and stable. I don't care about the missing video-bitrate
