Is UV damage to car paint actually a real problem in Dubai or are people just overthinking it?

So I had an interesting conversation with a guy at my office last week and now I cannot stop thinking about it. He pointed out that my car paint looked slightly faded compared to when I first got it and honestly I had not really noticed until he said something. My car is only about two and a half years old so I was a bit shocked because I expected it to look much newer than it does. He said the sun in Dubai is genuinely one of the worst things for car paint and that UV rays break down the clear coat over time even if you cannot see it happening day by day. He mentioned he had looked into Dubai Anti UV Paint Protection Film after noticing the same thing on his previous car and said it made a noticeable difference in how well the paint held up on his current one. I went through to understand more and it actually explained how UV exposure in this region is significantly more intense than in most other countries and that standard car paint without any protection starts losing its depth and shine much faster here than people expect. I always assumed regular waxing was enough but apparently wax only lasts a few weeks in this heat before it breaks down completely. Now I am wondering if getting proper film protection is something I should have done from day one. For anyone who has had UV protection film on their car for two or three years in Dubai, has it actually kept the paint looking fresh or do you still notice some fading over time?
