Did some practical shooting today. Most were shot under difficult conditions but the short conclusion is that while its a substantial improvement, the purple stuff still rears its ugly head
1. Very dark restaurant with halogen spotlights. The purple comes in the darkest shadow areas

2. Night sky. I avoided any contrasty lights and the purple seems to be kept at bay. If I recall, the purples horrid on the previous firmware on the same shot. f2, 1/10, ISO1000

3. Not sure if its the AE/AF locked wrongly or just the phone's noise reduction. No improvements on low light AF.
f2, 1/10, ISO1000

4. Loads of CA. f2, 1/30, ISO250

5. HDR mode seems to work a tad better. Previous firmware overexposes this shot a lot.

6. Again, shadow areas.

7. Street mixed lighting.
