The topics on this forum that discusses this matter of Luminosity Masking appearing to be part of PL are this one:
and this one:
In my first reply to the latter topic I said:
I got a fairly quick response from the UK ASA explaining that they couldn’t deal with the matter because DxO are a French company but that they would pass it on to their French counterparts, the Jury de Déontologie Publicitaire (JDP).
I then got a response from JDP dismissing my complaint, because they couldn’t find the relevant webpage.
I could still find page so I complained again to JDP, giving detailed, step-by-step instructions as to how to see the relevant wording that implied LM was available in PL, without the need for FilmPack.
This time they took notice and in their reply to me dated 29 Dec 2023, JDP said they were contacting DxO about the matter and would let me know the outcome. I’ve not heard from JDP since then but either DxO fixed the page themselves or they were required to fix it by JDP since as noted in this topic, the wording on the relevant page no longer mention LM as a feature of PL.
