I think there might have been some confusion on my side, @bielik01, due to the different types of rarity that have been brought up in this thread. I'd just like to clarify the issue that you and @Kulurak_CZ are reporting to ensure that we're all on the same page here.
Is the issue at hand that the "Full Master" trophy is a bronze trophy on PS4, but is shown as a silver trophy on PS5? If this is the case, I've reached out to our dedicated teams so they can take a closer look at this.
Or is the trouble you're experiencing based on the fact that the "Full Master" trophy is shown to be 1.49% rarity on PS4 on psnprofiles but is 1.6% on PS5? If this is the case, then you will need to contact either PlayStation Support or the support team for psnprofiles, as the rarity of a trophy (in this regards) is something that is calculated by PlayStation.
Once we've established the issue at hand, we can proceed with the appropriate investigation.
EDIT: Looks like you're faster than me, @bielik01! I apologise for not spotting your post edits sooner. I've notified our dedicated teams about the differing ranking (bronze vs silver) to see if we can get more information about this.
Thanks!
