Royal Enfield — Condensation inside head light

Address:

Siliguri Distributors, Sevoke road, Siliguri, West Bengal

I bought Thunderbird 350x on august 2019. It is still within warranty period and I have an issue with headlight. It was noticed that vapour is occouing after wet by rain. I took a picture of that on 22/08/2020 and shown to the service centre and requested to change the headlight. The Service manager has told me" the condensation is not that much to change it."
I want to know, why company is not mentioning the quanty of damage in their warranty policy?
