Not a technical answer but I would say more for looks.
The original houses go soft and absorb oil.
Normal silicone hoses will do the same and if you go for a nice colourful one , it will lose some colour and start to look dull.
You can get proper silicone ones which are fluro something lined and these will last .
Not 100% but I think jules sells the correct ones.
