Dehaze in LrC performing wildly different to Dehaze in Camera Raw

I shot a series of timelapse photos - each one 8 seconds in duration with a second between them. Imported them into LrC and made some adjustments. Sync'd settings across the images and noticed that some of them look wildly different in colour to the ones that followed.

 Narrowed it down to just two consecutive images - one that was ultra-blue and the following one that looked more purply (I was after a more purple look so the blue one was not expected). Adjusted one setting at a time and found the Dehaze was the culprit. A Dehaze of 88 (yeah, I know - quite high) on one image made it blue and a Dehaze on the very next image (just 1 second later) was purply. Odd.

 Opened each image in PS and did a Dehaze of 88 on each in Camera Raw and was very surprised to see that they BOTH looked purply. So, from my variations of settings and applications, it appears that under SOME circumstances the Dehaze under LrC performs wildly different from that in Camera Raw in PS, and Dehaze in LrC can result in wildly varying results even for two consecutive images.

Attached image shows the Camera Raw Dehazed version of image 9204, then the LrC  Dehazed version of image 9204 (note how the Camera Raw Dehaze differs from the LrC Dehaze), Camera Raw Dehazed version of image 9205, then the LrC  Dehazed version of image 9205 (note how the Camera Raw Dehaze is the SAME as the LrC Dehaze).

Pour pouvoir comparer LrC et CameraRaw, il faut ouvrir directement le fichier RAW original. donc depuis LrC, il faudra faire Ouvrir en tant qu'objet dynamique dans PS, sinon CameraRAw ser un fitre ajouté au développement initial fait dans LrC !
Est-ce ce que vous avez fait pour établir votre comparaison ?

To be able to compare LrC and CameraRaw, it is necessary to open the original file RAW directly. therefore since LrC, it will be necessary to make Open as dynamic object in PS, otherwise CameraRAw ser a fitre added to the initial development made in LrC!
Is it what you made to establish your comparison? (Sorry, Google translation !)

Yves is correct, but Google less so when it says 'dynamic object'. If you want to compare Lightroom and Photoshop/ACR, then you must compare raw files in both. You cannot send the image to Photoshop and then use Camera Raw as filter. In order to do it properly you need to use 'Open as Smart Object' and then double click the smart object to invoke ACR.

This may be related to or is the same as the issue in this thread.  It was acknowledged by Adobe 6 months ago so may be fixed someday.  Add you comments to the following thread.
