Are you sure, this is what exchange feed is? I am asking this because the screenshot I provided is from NSE website itself. So, the feed somewhere is getting mangled and tampered with. Is it either markup prices or some where during the phase of ingest, aggregate, stream triggers side of the technical infrastructure. Please check with your data lead/engineering teams here.
The daily OHLC at dhan & NSE website is same. The intraday charts and data is updated with ticks we receive from exchange and brokers may receive different set of data packets from each other, hence you may sometime find difference in intraday charts. The same has been explained in detail in post by @PravinJ
