Does iPhone 15 series support DP external display up to 4096*3072?

We want to develop a high resolution holo device connecting to iPhone 15 by DP/Type-C, and the holo content is cast to the device from our App rather than mirror from the iPhone screen.

A standard resolution of 4K, which is 3840*2160, is not as good as a 4:3 4K in terms of visual story telling.

And it will be a portrait device.

Thank you guys.
