difference between UBP 700 and UBP 800 sony 4k players

[Thready]

I got a sony tv for my dad and it has dolby vision. 

 

I see 2 Sony dolby vision 4k players. The UBP x700 and the UBP x800. I googled the difference but I can't find much. Is there a reason why the x800 is more expensive? Is the reason based on image quality? We just want to watch blu rays on it. I don't care about streaming or bluetooth or sound or anything else since our cheap soundbar plugs directly into the tv and we have a roku for streaming.
