I am very limited in use of applications by choice.
Why use lots of applications if the gain is little when you learn the main apps to use as good as possible?
That said, pure raw is like standalone viewpoint and filmpack in my opinion.
A “handout” or teaser to people who don’t need/want DxOPL eltite in full aspect.
Of of dxo perspective i wouldn’t set pure raw’s deepprime on par with PL.
Very close but not exactly the same in outcome and experience.
Why? Lot of people who buy dxopl just for deepprime and opticmodule and export as soon as possible to there editor of choice are easier to persuade to buy pureraw then full package.
There loss is then that they don’t get the other tools and therefore don’t be tickled to change opinion about the full package.
So to have some extra motivation to buy the full package make the full package just a bit better, in exported denoising , in advanged settings, in export types (dng) and formats (crops/resizing).
I am not familiar with the ACR module standalone and build in in LR but i guess they do the same.
I suspect the buyers are only interested in batchlike fairly straightforward exporting from raw to tiff or dng.
If dxo wants to make a Photolab elite mobile they need to scap the library function and search functions.
Ingest, select, edit, export, forget. Only dopfiles. Maybe a copyright iptc tamplet so you can instant stamp your id on all images.
Build for low impact on tablets and laptops. No designated folders as in you need to copy first to hd ssd, just directly from sd and export to external drive.
You could easy make a setup choice so you can install as normal or mobile , because you have 3 installs.
