iPhone 13 few months old has lost most of the green color

I saw the phone going very low bright in the days before without a good reason

ia have turned off auto tone an tha has helped a bit reducing the large amount of red but I still have very few green and all images are very dark

i have make sure all color filters are off and auto tune is off night color is off I can’t nearly read with this colors and some time the full brightness turns down to zero and I can’t see anything.

i. Out from a retailer in Peru so what can I do? The retailer only gave me one month guarantee.
