P: Add Histogram when shooting

I love lightroom camera support RAW format, that improve iPhone photo quality so much better!

Can you show histogram when shooting? Lr's RAW always overexposured +0.7EV (Why?)

And support shoot in 2x lens? Like BlackMagic Cam app native support 0.5x, 1x, 2x, 5x lens, not digital zoom.

(I'm using iPhone 15 Pro Max)
