A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
The apps on the Ipad should be color managed so the P3 display is not the problem.
What display do you have and how have you calibrated and profiled it?
Do you have true tone turned off on the Ipad?
Have you matched brightness and are you comparing them under the same viewing conditions?
Is it even possible to calibrate an iPad? I’ve read that the iPad Pro 12.9 M2 had the reference mode where you can set your display to various colour spaces, including sRGB. But AFAIK you have to calibrate your monitor from time to time because it changes over time. I don’t know if you are able to do this with an iPad.
But AFAIK the sRGB lays inside the P3 and P3 only extends some colours. Please correct me on this if I’m wrong.
Calibrate, no, but you can profile the display. Probably not necessary though, and the apps for profiling weren’t very good last I checked. In my experience the IPad displays shift very little over time. Like, I had to recheck the results on a one and a half year old IPad Pro, because I couldn’t believe it. Almost no change whatsoever.
