Glenmorangie - Dark colour of whisky compared with your standard colour

My son bought Glenmorangie whisky from Abu Dhabi airport on April 14, 2022. Yesterday I was invited by my friend for dinner. I presented Glenmonagie bottle to him in sealed box. He opened the bottle and poured 45 ml in each in 2 glasses. After a while he told me whisky colour is dark and told me it is not a standard colour of Glenmorangie. He got his Glenmorangie bottle and compared with mine. I felt insulted since perhaps I thought I got him duplicate Glenmorangie whisky. I want you to investigate and give your full report so that I can convince my friend that I offered him genuine Glenmorangie.
