Social media optimization

I'm a content creator. I use the S23 Ultra to make videos, but the problem is that when I upload videos to Instagram, the quality is compromised. Recently, I purchased an iPhone, and now I share my videos to the iPhone first and then upload them to Instagram. My point is, what is the purpose of buying Samsung's premium phone when it doesn't perform well for social media apps? I request Samsung to optimize apps for their phones to meet users' requirements.
