Title: Inconsistency in Lens Corrections for Different File Formats
The Lens Corrections results in Lightroom Classic/ACR are inconsistent across different file formats, particularly between raw files (eg.ARW) and HDR files (-HDR.dng), where Distortion Corrections and Vignetting Corrections differ, leading to imperfect alignment during further post-processing.
This issue is especially pronounced in photos taken with zoom lenses.
RAW files:

HDR files:

A typical example:
In the same cityscape night scene, I took a series of [bracketed exposure photos] for creating a [High Dynamic Range background] and a series of [time-lapse photos] for maximum value synthesis of [TAIL LIGHT TRAILS]. I merged the [bracketed exposure photos] to generate a -HDR.dng, made slight adjustments, and then synchronized the photo settings with the [time-lapse photos], exporting all as TIF files for manual post-synthesis.
However, when I overlapped the HDR photo with the time-lapse photo, I found that the lens corrections were not consistent, especially with noticeable deviations at the edges of the image, which prevented me from effectively using Photoshop's mask tool to delineate the areas I wanted to preserve.
This issue has been bothering me for a long time, causing my workflow to be frequently interrupted.
Is there another way to make Lightroom Classic apply the same Lens Corrections to photos of different formats?
