P: Auto Sync of changed Denoise slider recomputes Denoise instead of just changing the slider

[johnrellis]

When multiple photos are selected in Develop, all with Denoise already computed, changing the Denoise amount slider with Auto Sync on recomputes Denoise for the target photos rather than just changing the slider. The same problem occurs with Distraction Removal > Reflections. In contrast, changing the Lens Blur amount slider doesn't cause Lens Blur to be computed.

To reproduce on LR 14.4 / Mac OS 15.5:

1. Select two unedited raws and edit the first in Develop.

2. Toggle on Auto Sync.

3. Click Detail > Denoise. Observe that Denoise is computed for both photos (correct).

4. Change the Detail > Denoise slider to 70. Observe that Denoise is recomputed for the second photo (incorrect).

5. Repeat steps 3 and 4 for Distraction Removal > Reflections and observe that changing the slider in the first photo recomputes Distraction Removal in the second photo (incorrect).

6. Repeat steps 3 and 4 for Lens Blur and its Blur Amount slider. Observe that changing the slider in the first photo auto sync's the change in slider to the second photo without recomputing Lens Blur (correct).

A welcome improvement, but there are problems with using Presets for Denoise:

Create a Preset to apply only Denoise with an Amount 80.

Use Auto Sync to manually Denoise a selection of photos.

When completed, with Auto Sync still enabled, apply the Denoise Preset to the selection. The Denoise is unnecessarily recomputed on the entire selection of photos that have already been Denoised. Work still to be done here.

Once the Preset has been applied, with Auto Sync still enabled, change the Denoise Amount to 30. When the update to the selection has completed, apply the Denoise Preset again to the selection. An updating message is displayed, but the Amount doesn't change for any of the selected photos. Another issue to be fixed.
