Color shift when denoising ProRAW DNG (iPhone 15 Pro)

Just updated to LRC 14.0 and wanted to test Apple DNG denoise, something I've been waiting for for so long. And immediately noticed a color shift, well visible in this screenshot (I hope). Sky in the left (original) photo has more blue tones, denoised version is more grey.

The team had a chance to look at your sample files—thank you. The Denoise operation allows for slight color shifts, which are typically global and can be handled with a simple tint adjustment. If the area is more regional, a subtle Point Color adjustment can correct. 

This is not something new. Since Denoise first launched, subtle color shifts have been possible.

Well, yes, but you fix it at the root? It's a bit unexpected (as it doesn't happen with other raw formats), illogical and therefore annoying, you know.

Would you be willing to Export this file as a DNG and share it with us so the engineers can look at it?

Which file do you need? I already have the original Apple .DNG, do you want me to export the resulting shifted file from a LR to a .dng as well? And where can I submit it?
